Tamm

"Tamm" is the Estonian word for an oak tree. It's pronounced almost like my name (Tom), but with an "ah" sound. There is a tradition in Estonia of preserving and naming the biggest trees of each major species, and also for large groves or unusual trees. My map of Estonia contains perhaps two hundred such marked trees, and all the ones I've visited so far (something like 30 or 40 of them) have signs or other markings, and usually some parking and a path to the tree or trees. I have no idea of the origins of this custom, and I have not yet ever found anyone else visiting the trees to ask. But I like it, and I've very much enjoyed finding and visiting various trees.

The tree at right above is called the Mäe-Lehtsoo Tamm, and it's located near the small lake (Punde) pictured at right, near the town of Urväste in south-central Estonia. If I understood the sign correctly, it is the second-largest oak in all of Estonia. The area around the tree had recently been cleared of brush, along with the hillside above it, giving a clear view of the entire tree. This was a nice presentation, but the tree itself looks like it's not in such good shape. There are many large broken branches, and much of the tree looks quite sickly.

This oak tree is the largest one in Estonia — a very famous oak called the Tamme-Lauri Oak. If you enlarge the picture of the sign at right, you can read all about it. A drawing of this particular oak adorns the Estonian ten-kroon note (Estonian currency is denominated in kroons until they adopt the Euro, scheduled in early 2006).

Where in the world?

I'm leaving tomorrow morning (Thursday, 8/11) for an extended mostly-business trip, to Tallinn, Estonia and St. Petersburg, Russia. Blogging will be intermittent, and probably mainly on the weekends.

Those of you who know me also know that these are places that I have been visiting often (usually at least two or three times a year, sometimes more) since 1994 — Tallinn more often than St. Petersburg. I'll be spending a working week in each city, in my employer's software development facilities.

This coming weekend I'm going to spend a couple of days alone, sightseeing in southeastern Estonia near the towns of Võru and Rouge. With luck, the weather will be good and I'll even have a few photos to post.

The following weekend I'll be traveling by car from Tallinn to St. Petersburg, with two or three of my fellow workers. We'll be taking the long way, down through the same southeastern part of Estonia and then back up through a part of Russia that will be new to all of us.

Then after that second working week (in St. Petersburg), I'll be traveling back to the good old US of A — but not quite back to California. I'll be stopping in to see my folks for a few days, at their home in south-central New Jersey (yes, I'm related to someone who lives in New Jersey — get over it!). This will be both a for-fun visit and an "IT upgrade" visit — my mom's computer is badly in need of an upgrade, and I'm going to be hooking them up to a broadband Internet connection (via Comcast cable).

And then at at long last I'll be heading home. I'll be "boots on" to Jamul late on 8/31...

Mustard

Let me make one thing perfectly clear: I hate mustard. It's the worst weed in my home's environment, by far. There are two common species in my yard, so far as I can tell: black mustard (brassica nigra) and shortpod/mediterranean/hoary mustard (hirschfeldia incana). See this very useful mustard page, from which I shamelessly stole this photo. The photo at right shows both species growing side-by-side, with the h. incana in the foreground.

My mustard hatred is particularly keen at the moment, as I've just come back inside after battling the umpteen million plants in my yard. My current method is very hard work, but quite satisfying, as the mustard plants are mechanically chopped from the ground, pieces flying in all directions. I'm using the top-end Husqvarna weed-whacker, fitted with a three-toothed steel blade (that wimpy plastic cord doesn't work on mustard!). It's quite powerful, with (I believe) a 2.5 horsepower gasoline engine. What makes it hard work is that (a) you have to dig the rotating blade into the ground to get all the leaves chopped off (particularly for the h. incana plants), and (b) it's 90 degrees plus outside. Over the last two mornings, before it got too darned hot, I cleared about an acre and a half of these disgusting, hideous, obnoxious things.

That's the good news. The bad news is that past experience suggests to me that they'll be back, as strong as ever, within a week or two. The mechanical removal method — while satisfying — isn't really very practical, it seems. So this morning I set out to investigate herbicides.

And I discovered almost nothing in the way of advice on what kind of herbicide to use on mustard. I did find a few articles about "broad spectrum" versus "broadleaf" weed killers, but it's not 100% clear to me whether mustard is or is not considered a broadleaf. There was a lot of discussion about h. incana (in particular) and genetic modification; apparently it easily hybridizes with some crops (especialy rapeseed), creating the danger of spreading herbicide-resistance genes to the same species we're trying to control.

So...I'm off to Home Depot to see if they carry any herbicide that specifically targets mustards. I'm not particularly optimistic about this, as I'm beginning to believe that mustard is the one plant that's likely to survive anything up to and including a nuclear holocaust...

APOD

APOD brings us...

Will it be curtains for one of these auroras? A quick inspection indicates that it is curtains for both, as the designation "curtains" well categorizes the type of aurora pattern pictured. Another (informal) type is the corona. The above auroras resulted from outbursts of ionic particles from the Sun during the last week of 2001 September. A polarity change in the solar magnetic field at the Earth then triggered auroras over the next few days. The picture was taken on 2001 October 3 as fleeting space radiation pelted the Earth's atmosphere high above the Yukon in Canada.

Rescued!

Said Yelena Milashevsky, wife of the trapped Russian mini-sub AS28, about learning that the crew had been rescued safely:

My feelings danced. I was happy. I cried.

What she said.

The news is reporting that the Russians have been very gracious about thanking the international efforts that helped free the mini-sub from its entanglements — most especially, of course, to the British, as their Scorpio remote-controlled submersible was first on the scene and actually cut the cables. Defense Minister Sergei Ivanov, who went to Kamchatka to supervise the operation, praised the international efforts. "We have seen in deeds, not in words, what the brotherhood of the sea means."

An altogether joyous ending for something that could have ended in much differently...

Sub down

The story, as reported by The Age (Australia):

A Russian mini-submarine with seven sailors aboard was trapped on the sea floor off the Kamchatka Peninsula on Russia's Pacific Coast after becoming caught on an unidentified object, navy officials have said.

Navy authorities were trying to determine why the military vessel, called a bathyscaph or mini-submarine, was stuck some 190 metres below the surface before starting rescue efforts, Pacific Fleet spokesman Captain Alexander Kosolapov said in televised comments.

He said it might have been caught on a cable or a fishnet.

Kosolapov said there was contact with the sailors, who were not hurt and that authorities were preparing to send down a similar vessel to assess the situation.

Conflicting reports said there was enough oxygen in the vessel to last between one to five days.

Kosolapov said there was likely enough air to last four days, because such vessels typically have oxygen supplies for 120 hours and the accident occurred when it was launched from a rescue ship during a combat training exercise, the Interfax news agency reported.

AP reports have several facts different, in particular saying that there is just one day's oxygen on board. Let's hope the AP has got it wrong, because one day is not a lot of time to put a rescue effort together. I could find very little online about the Priz class of submarines. From Jane's, in a section on rescue submarines:

Little is known about Russia's systems, one submersible of the Bester and five of the Priz class, which were involved in the failed rescue attempt on the Kursk. The Priz is thought to be operable either manned or unmanned, but is restricted by a battery endurance of just three hours. An upgrade has been proposed that will allow the Russian systems to dock with damaged submarines and improve their navigation equipment.

I found several references to either one or two Priz-class submarines being used in the Kursk disaster, attempting to rescue the crew. From my own time in the Navy (now almost 30 years ago), I know that our rescue submarines depended on a specific hatch configuration to "dock" into; our submarine fleet was all equipped with these hatches. I don't know if the Russian rescue subs depend on such specific equipment (or indeed, if our own still do). I'm rambling a bit, but what I'm thinking is that a sub-to-sub transfer sort of rescue is a really tough challenge, and possibly dependent on equipment configurations that may or may not be present. I'm hoping that it's possible to untangle the propeller of the down sub, so that it can get to the surface on it's own — that seems like a much more likely scenario than a transfer.

Whatever the mode of rescue, our fervent hope is that the rescue is successful and the seven trapped sailors can breathe the fresh air on the surface once more...

Open source

A very interesting article from Paul Graham. An excerpt:

So these, I think, are the three big lessons open source and blogging have to teach business: (1) that people work harder on stuff they like, (2) that the standard office environment is very unproductive, and (3) that bottom-up often works better than top-down.

I can imagine managers at this point saying: what is this guy talking about? What good does it do me to know that my programmers would be more productive working at home on their own projects? I need their asses in here working on version 3.2 of our software, or we're never going to make the release date.

And it's true, the benefit that specific manager could derive from the forces I've described is near zero. When I say business can learn from open source, I don't mean any specific business can. I mean business can learn about new conditions the same way a gene pool does. I'm not claiming companies can get smarter, just that dumb ones will die.

Read the whole thing — it's fascinating.

A beautiful ad

Probably not the kind of comment you'd ever expect me to make! But take a look at this moving and effective ad for a Ford Mustang, and see if you don't agree with me.

Ford may have found a way to get me to look at their cars, which ordinarily I wouldn't even consider (we own a Toyota LandCruiser and a Toyota T-100, and love them both). Someone at that company has their act together. This ad is tasteful, very supportive of our troops, and yet still effective.

Hat tip to Gateway Pundit — and check out the moonbats in the comments while you're there for the view from the other side...the other side of the door to the lunatic asylum, that is.

Clear Lake Panorama

This is a stitched-together panorama, made of six individual shots. Each of the sub-pictures was made with identical exposure settings, handheld, in vertical orientation (e.g., the long axis of the picture is vertical).

I've made quite a few such composite pictures; with modern tools (I use PhotoStitch, from Canon) it is both quite easy and gives very nice results. This particular tool has two independent methods for orienting pictures: an automatic mode (what I used here) that somehow finds the pieces in adjacent pictures that are overlapping, and a manual mode that lets you precisely identify the overlaps. Usually I use the manual mode, as the results are generally better. This time, I could not spot any obvious flaws from the automatic mode, so I left it alone.

The place is Clear Lake, in the San Juan mountains of southwest Colorado (see my post here). As usual, click on the photo for a larger view.

'Intelligent Design'

The story:

President George W. Bush stirred the debate on the teaching of evolution in schools when he said this week that he supported the teaching of alternative viewpoints - such as the theory of Intelligent Design - to help students "understand what the debate is about".

"I think that part of education is to expose people to different schools of thought," Mr Bush said in comments to five Texas newspapers on Monday. "You're asking me whether or not people ought to be exposed to different ideas, the answer is yes."

Although Mr Bush did not explicitly endorse the concept of Intelligent Design, which contends that certain features of biological systems are best explained by an "intelligent" cause rather than by natural selection, such influential groups as the National Academy of Sciences strongly oppose the teaching of ID in schools.

The story above (excerpted from the Financial Times), with minor variations, was reported all over the MSM yesterday. I first read it in a rather hysterical post on a liberal blog, where it was interpreted as Bush was about to force all schools to teach 'intelligent design' (which I put in scare quotes because I do not believe it is a legitimate scientific theory). On reading in more sober reports what Bush actually said, I am slightly comforted...but only slightly. Tigerhawk captures my personal response best in his excellent post titled "Sigh", here excerpted in its original entirety (it has since been updated):

Why, oh why, must our President, who is right about so many things, insist that idiocy is a form of intellect.

Thanks, Tigerhawk, for that succinct summary. And for the pointer to Charles Krauthammer's column in Time Magazine on the subject. Mr. Krauthammer doesn't mention Bush's remarks, but forcefully makes the argument that it's a bad mistake to teach something that is faith (meaning 'intelligent design' as if it were some form of science (such as evolutionary theory). And he gets it exactly right when he calls 'intelligent design' a "tarted-up version of creationism."

On the other hand, there are a few conservative voices supporting Bush's position. Right-Thinking Girl says:

Though I am positive that Bush's detractors will no doubt start crying "theocracy!" at the mere mention of Intelligent Design, I think this is a good idea. I am not interested in having Christianity taught in public schools, per se, but I believe that schools are places to challenge one's own body of knowledge. If evolution is perceived to be the "anti-religion", I think that there should be a counterweight to that. Though Intelligent Design is not Christian in nature, it does encourage the possibility of a Supreme Being. Good for Bush, speaking up on such a controversial subject.

Well, maybe. I'm not buying the "'intelligent design' isn't Christian" notion — so far as I can tell, it is entirely the construct of fundamentalist and radical Christians, exactly the tarted-up version of creationism that Mr. Krauthammer paints it as. Right-Thinking Girl's point about the need for a counterbalance might make sense in some kind of philosophy curriculum, but certainly not in a science classroom. Science is about truth, and truth is inherently "unbalanced" in the sense she means.

And then there's GrrlScientist's rant at "Living the Scientific Life":

Well, if we are going to be truly open-minded about this, bushco would propose equal time for ALL other creation myths floating around out there.

But the problem with this unexpected rush of open-mindedness is that bushco once again misunderstands science: science is not about presenting different creation mythologies as if they are Flavors of the Week at the local ice cream shop. In fact, there are thousands of peer-reviewed research articles that provide yet more evidence for the Theory of Evolution but there is absolutely no scientific credibility, and absolutely no data, that support ID/creationism. How long will it take before this simple fact finally sinks in? In view of this fact, forcing teachers to present ID in a science classroom is absolutely ludicris.

I regularly read GrrlScientist's blog because she shares an interest of mine (birds). I'm an amateur bird-watcher; she's a scientist, an ornitholigist if I'm not mistaken (and she's looking for a job, if any of you have one available). We do not share much common ground in politics, however. Every once in a while, she'll post a rant about Republicans in general, and Bush in particular, which mostly I've ignored except for their entertainment value, as they've been along familiar themes and lines of argument. This time, though, I do find some common ground with her rant. I admit to some discomfort at that realization <smile>.

My hope is that Bush will wake up to the bad politics his comments represent, and will make some clarifying remarks to defuse the negative reactions from (what I fervently hope is) the majority of his base. Including myself.

Pete and Trudy

Went down to Paul Cingota's today and took some group pictures of the agility class that included Pete and Trudy. The picture is a going-away present from the group, because Pete and Trudy are moving — to the Bahamas! There is a medium-sized version of this image here, and a truly enormous version of it here. In addition, all the raw pictures are available on my personal site, here.

Stony Pass and Minnie Gulch

The events described here took place July 21st.

Well, this is it — our last day in the San Juan Mountains. For this day, we chose to go back to the best flowers we'd seen on the whole trip, at Stony Pass. We left early, and then had time to investigate one new place, a gulch near Stony Pass called Minnie Gulch. Stony Pass was even better this time than it was the first time, and Minnie Gulch was even better. The scenes at right are from both places.

Left-to-right: fireweed, columbine, a daisy or aster, and an unknown "purple spikey thing". The fireweed is an invader, and it's common but here not apparently threatening any of the local species. And it can be quite beautiful. The columbine is the glory of the San Juans; a jewel of a flower that is very common here, especially on steep hillsides. The colors vary from almost white to deep lavendars and blues. Various kinds of yellow daisies and asters abound here, some of the massing into displays that can be seen for miles across the valleys, and often the brightest spot in any meadow. The purple spikey things are abundant in a variety of settings, but most common of all on steep, well-drained hillsides; often seen in conjunction with columbine.

Left-to-right: columbine, daisies, columbine, a daisy close up. On the way up Stony Pass, I spotted a gorgeous patch of daisies high on a hillside above us. We parked, dad read, and I trudged up the hill with my camera gear. A good number of these photos came from that walk up the hillside. The grade here was over 45 degrees from the horizontal, and the footing a mix of talus and loose soil. Treacherous! By carefully steeping just uphill from established plants, I could use the soil stabilized by their roots as a series of "steps" to get up the hill, and that's exactly what I did. Had I fallen, I'd likely have traveled quite a ways down that hill before I could manage to stop, but somehow I managed to avoid any klutz maneuvers, and stayed upright all the way up (perhaps 300' of altitude) to the daisies. Each step was a delight, though, with all the other flowers on the hillside.

Left-to-right: Indian paintbrush, larkspur, Parry's primrose, Indian paintbrush. The first paintbrush was common, though this is an unusually vibrantly colored specimen. The larkspur, with 4 to 6 foot high flower stalks, was one of the most common flowers in all the San Juans, probably second only to cowslip. This Parry's primrose was for some reason in prime, next to a brook that was below timberline — while other specimens two or three thousand feet higher were well past prime, and even in seed. The last paintbrush was an unusual species that we saw only in one place, though there was a fairly large colony of it there.

Left-to-right: red sedum, unknown, and Parry's primrose. This red sedum had lots of color variations, from a washed-out, almost pastel red to a very deep red that was almost black. The bright reds, like the one pictured, against the dark green foliage, was a favorite of mine. It's very common in the San Juans. The unknown flower was also very common, mostly in a much darker purple shade. This specimen (and a surrounding colony) was an attractively different one. The Parry's primroses turned out to be better (e.g., more prime) at Minnie Gulch than anywere else we'd been. The brook and falls at the top of Minnie Gulch (see below) was the best of the best.

Left-to-right: larkspur, cowslip, unknown. The larkspur are beautiful almost no matter how you see them, but I think backlit (as here) is perhaps my favorite way to view them. Their tall flower stalks made a backlit presentation a fairly common occurrence, and we enjoyed them all. A close runner up, though, would be masses of larkspur viewed frontlit in the early morning sun, with a little dew on the flowers. Cowslip are most attractive, no doubt about it, viewed en masse with a little distance (20 or 30 feet is about right). But these individual flowers caught my eye in some unusual filtered and shadowed lighting, under a forest canopy. In the sunlight, the blues of the foliage rival the blues of the flowers, but certainly not here. The unknown yellow flower was mostly seen along the roads, making us thing it may be an invader, spread by the manure of the draft animals. But it's common enough, and can be quite attractive.

At the top of Minnie Gulch, just past where the road is blocked to vehicles, there is a brook that tumbles almost 1000 feet vertically down a steep hillside. At the bottom, the altitude is around 12,000 feet. The four pictures at right, and the four just below, are all taken from the bottom 200 feet or so (vertically) of that brook's path. It is an intoxicating walk along that stream — an unending series of small falls, rapids, and flower displays. Unfortunately this was too much vertical work for my dad, so he didn't get to share this bit with me.

Parry's primrose and the fragrant white flower we love were very abundant here, and many of the Parry's were in prime. Toward the top of my walk there was a larger falls, perhaps 10 or 12 feet in drop, that provided a particularly attractive scene. As I was taking these photos (all on tripod, with time exposures up to a few seconds), I was considering hiking above these falls, where the hillside suddenly got much steeper. But the heavens opened as I pondered, and with rain spattering all around me and lightning in the middling distance, I decided it would be wisest to skedaddle down the mountain. Which I did, zooming past all the marvelous scenery that I'd just hiked up through so laboriously. What a memory!

I'll end this post with a couple of mammalian photos. At left is a marmot, more cautious and wary than most we encountered on this trip. Along a side road on Minnie Gulch he was munching on something in a meadow near the road. When I stopped to see if I could grab a picture of him, he high-tailed it for a nearby rock pile (the bottom of a talus slope). He bounded 50 feet or so uphill, disappeared into the rocks, then popped up as you see in the picture, giving me the proverbial hairy eyeball. He did not relent until we packed up our things and left. Much lower down on Minnie Gulch the road travels alongside a stream in a fairly steep gorge (perhaps 15 or 20 degree slope). For a long section of this descent, the stream's natural flow has been re-engineered by a series of beaver dams, forming a long series of terraces. I'd guess that the average elevation difference between adjacent terraces was only four or five feet. The typical terrace was much like the one at right: a small, elongated pond containing a beaver lodge. Looks to me like the beaver recovery program is working rather spectacularly well!

Yankee Boy and Governor Basins

The events described here took place July 20th.

Today we decided to revisit the first area we explored on this trip: the Yankee Boy and Governor Basin area. The flowers had been very good nearly two weeks ago, but not yet completely out at the higher (alpine) altitudes. We hoped to see more alpine flowers this time, and perhaps to get a little further into Governor Basin (where we had been stopped by a large snowbank before). The photo immediately at right is along the brook that emerges from the Blue Lakes (which were above us and out of our sight), tumbling through a sub-alpine gulch and bordered by lush wildflowers. We took a half-mile or so walk along this stream that was most enjoyable. At far right is one of the small lakes that lies near the highest point reached by the road in Yankee Boy Basin, at about 12,600 feet altitude. There is a footpath that continues on to Blue Lakes and Mt. Sneffels summit, but we did not take these. While there were a few more alpine flowers out, it wasn't a dramatic change from our first visit. But the sub-alpine flowers more than made up for the disappointment on the alpine flowers...

Both of the flowers at right are mysteries to us. At far right, the white flower is one that when we first spotted it a few days ago on the forest floor, we thought we'd discovered something unusual. We didn't know the flower, and it was uncommon. Within a day or two we were seeing it everywhere, and nowhere in such abundance as along the roads in Yankee Boy and Governor Basin, just below timberline. It has very little fragrance, grows in bunches that sometimes mass into large arrays, but has very oddly shaped individual blossoms with twisted petals. The other flower really was unusual; we saw it in only a couple of places near newly melted snow. The violet color stands out dramatically against the otherwise not-yet-sprouted background. They're very tiny and low; big enough to spot easily, but not massing up like so many other flowers here do.

At far right is another scene by the brook we walked along. Each time we turned a corner on this walk, we were presented with another rock garden like this, full of mixed wildflowers of all colors, but trending strongly toward the blues and lavendars. Down near the brook itself, the scene was dominated by the fragrant white flower we love so much, and the deep violet of Parry's Primrose. At left, from a much lower altitude, is a mature pussy willow seed "pod", exploded and letting seeds get carried along by the wind. There were several species of willow very commonly found both above and below timberline. As you'd expect, most of these were found near water, including substantial stands of dwarfed willow at the higher, alpine altitudes. These won't be mature for some time yet, their season being delayed by the cold that comes along with altitude.

As usual, you can click on any photo for a larger view.

Imogene Pass

The events described here took place July 19th.

Imogene Pass is a very high (13,114 feet) pass between Ouray and Telluride. The first day we were in the area, 12 days ago, the road to the pass was closed by snow. By today, enough had melted that the road could be plowed. At right is the summit, looking north. The 360 degree view here was a spectacular tableau of rugged mountains, blue sky, and alpine vistas. According to one of our guide books, Imogene Pass is the second-highest pass (with a road) in the continental U.S. This is easy to believe when you're up on it, looking around at tall mountains that lay below you, and breathing the rareified air. We decided not to head down toward Telluride, as the vegetation on that side looked sparse and the tourists promised to be thick.

The trip from Lower Bird Camp to the pass itself was a new one for us, and it had one big surprise: the road follows a steep gulch with plenty of water flowing in it, making for many waterfalls and rapids. We had a good time knocking about in the area of the waterfalls. That water also meant the plant life was abundant and lush. The yellow flowers pictured at right were common in areas where snow had recently melted, right along side a white marigold. The violet flowers (which were more commonly a darker, almost black color) were very common all over the San Juan mountains, in a variety of conditions. We didn't know what either of these flowers were.

On one short walk, we hiked alongside a tumbling brook that was bordered by thickets of willow. In one of these thickets, the bird at right (an adult male Wilson's Warbler) was very curious about who I was and why I was in his territory. Naturally I did not have my telephoto with me on this walk, as I wasn't expecting to encounter any creatures of the birdly persuasion. But he was so close that even with my macro lens (which actually is a 100mm telephoto) I was able to get a photo good enough to identify him with. He stayed with me all the way to the edge of his thicket, but not a bit further. The scene at right is taken right nearby his thicket, where the brook emerges into a meadow that was just blanketed with wildflowers. The white flowers in the foreground are very fragrant, and only grow in very wet places (such as the banks of a brook). They were one of our favorites. The blue flowers in the background are cowslip, which was extremely common in this area.
