So, there I am, driving along in Edmonton, Alberta. I come to a stop light on Fort Road, look to my right and I see this:
Is that a building with longitudes written on the roof?!?!
And what are these longitudes? 9° 49’ W—that’s nowhere near Edmonton! Nor is 123°30’ E. What’s … going on here?
A little sleuthing via Google Maps later revealed that this was the Kathleen Andrews Transit Garage. It’s owned by the Edmonton Transit Service, which operates all of the buses and light rail in the city. But the rooftop details were part of an art installation by Thorsten Goldberg called 53° 30′ N. Each of the five structures on the roof (architecturally called lanterns) displays a longitude that directs us to a place on the earth at the same latitude as Edmonton: 53° 30′ N.
And—added bonus for shaded relief fans—that piece of terrain is then represented in 3D on the end of its lantern. Look carefully at the photo. There they are! They look for all the world like pieces of DEM rendered as Triangulated Irregular Networks in Blender.
For someone who spends a lot of time looking at terrain, this is the best kind of public art ever!
Before I go on, here are the five longitudes, in case you want to figure out for yourself where they are…
9° 49’ W
159° 08’ E
168° 10’ W
119° 26’ W
9° 49’ W
Mweelrea, County Mayo, Ireland
An unnamed gooseneck of the Amur River, which forms the border between China and Russia.
159° 08’ E
The 2958 m Kamchatka volcano volcano, Zhulanovsky (Жулановский), Russia.
168° 10’ W
Okmok Crater, Umnak Island, Aleutian Islands, Alaska
119° 26’ W
Mt Chown, Alberta
Here are some more images of the building from a CBC article.
“The collected mountain landscapes are Mount Chown at 119°25‘8.24“W in Alberta, named by the Methodist minister Samuel Dwight Chown; the crater with Mount Okmok, a volcano on Umnak Island, the Aleutian Islands in Alaska at 168° 6‘22.60“W; the Zhupanovsky Crater on the Kamchatka Peninsula at 159° 8‘25.04“E; an unnamed landscape near Dacaodianzi, Heilongjiang Sheng at 123°17‘54.95“E in China; and finally Mweelrea, the highest point in the province of Connacht at 9°49‘47.59“W in County Mayo on the west coast of Ireland.”
Kudos to the City of Edmonton and its Percent for Art policy, which stipulates that one percent of construction budgets goes to public art! This must be one of the most fun geography puzzles ever.
I’ve been reading Gottfried Merzbacher’s Central Tian Shan which was published in 1905. (Archive.org has a free copy here.) This German geologist spent 1902-3 in the Tian Shan exploring valleys, noting strike and dip, and, among other things, trying to figure out the actual location of the peak Khan Tengri. This 7000m peak was not marked correctly on the 40-verst Russian map he was using. (40-verst maps were a series at 40 versts to the inch, or 1:1,680,000.)
While reading Merzbacher’s account, I looked at my map of Charles Howard-Bury’s journey in the Tian Shan (posted previously) and discovered I too had Khan Tengri in the wrong place!
So I did a little homework to make sure I had it moved it to the right place, because not being sure where Khan Tengri is located should be the kind of problem they only had 100 years ago, right? Well, maybe not. Let’s compare Google maps, on the left, and Bing maps on the right.
Wow, that’s some pretty serious difference. Not only is Khan Tengri in a different place (relative to the glaciers, for example), but the Chinese-Kyrgyz border is also in a different place. In Bing’s world the border runs atop the highest peaks, while in Google’s the upper portion of the South Inyl’chek glacier is actually in China.
Bing, by the way, is using Russian peak names, like Pobedy Peak, while Google has its Kyrgyz name, Jengish Chokisu.
Turns out that OpenStreetMap has the same border Google does; but Yahoo and Here have the border that Bing does!
A quick web search reveals that China and Kyrgyzstan settled their border disputes in 2009. It’s likely that one of the sets of lines we see above dates from prior to that settlement, and one from after. But which is which?
Administrative boundaries downloaded from GADM and DIVA indicate that Bing/Yahoo/Here are actually more up to date.
But as far as the location of Khan Tengri is concerned, I’m afraid Google/OSM are correct.
In chapter 3 of Charles Howard-Bury’s Mountains of Heaven, written in 1913 but published in 1990, the author details a ten-day journey on Russian post roads. (I discussed a map I made of the central part of his journey in this previous post.)
He arrives in the town of Semipalatinsk by steamer (coming up the Irtish river from Omsk) on June 7th,1913, and then he and his servant John Periera prepare for this overland journey by buying a tarantass, a type of 4-wheeled cart. Although in the post road system one would typically receive a new horse and tarantass at each post station (about 20 to 30 versts apart — a verst being 1067 metres or slightly longer than a kilometre), Howard-Bury has strategized that by providing his own tarantass he’ll avoid repacking the heaviest boxes at each change of horses.
The list of luggage is revealing. A valise and bedding, camp bed, bath, table and chair, baking powder and jam in tins, photographic films, a few varieties of soups, some condensed milk and “one or two delicacies such as sardines and potted meats;” two rifles, a shotgun, and ammunition; tea, bought in Moscow; and “a plentiful supply of literature.”
They depart Semipalatinsk on June 9th in the late afternoon. The first three days of post-road travel takes them to the town of Sergiopol, covering on those days, by his reckoning, 47, 101 and 124 versts respectively (53, 108 and 132 km). Mountains of Heaven does not give us a detailed map, but it’s not hard to determine the route to Sergiopol, which is an old name for the town of Ayagoz, Kazakhstan. By following the most direct road between the two towns on Soviet maps made in the 1980s, I can get just these distances that Howard-Bury reports.
After Sergiopol, things get a bit trickier. Howard-Bury and Pereira stop sleeping at post stations and the author takes to giving distances from one midnight to the following midnight. At the end of day 6, they are one stage beyond the town of “Kapal,” which it’s easy to be confident is the still-extant town of Kapal, Kazakhstan. But by which route did they get from Sergiopol to Kapal?
Howard-Bury mentions all sorts of landmarks over these three days, which we can try to match up with the terrain. He gives the travel distances as 140, 153, and 105 versts, respectively (150, 163, 112 km). The most crucial landmark is a town named “Lepzinsk,” which they pass through towards the end of Day 5. If we can locate this Lepzinsk, we’ll be close to drawing the right post-road connection from Sergiopol to Kapal.
Here are the clues which Howard-Bury gives us.
Day 4 (140 versts, starting at Sergiopol):
For some distance we followed the valley of the Aksu, crossing and recrossing the river…
Towards evening we got into flatter country again, where the plains were covered with wormwood as far as the eye could see.
Day 5 (153 versts):
We continued travelling all night but at eight o’clock in the morning had only succeeded in covering 32 versts since midnight, owing to the sandy nature of the soil…
We had to cross several arms of the desert which stretched across the road from the west in broad rivers of sand several miles wide…
We now had to cross a range of rocky hills…
We are now not far from the shores of Lake Balkhash… there is good fishing to be got at this end of the lake where the Sergiopol River flows into it.
Low rocky ridges alternate with broad grey and yellow plains…
Further on the plain became at times white as snow from the alkali in it that had come to the surface…
Towards evening we got our first glimpse of lofty snowy mountains to the south…
The going was very sandy and heavy. We kept crawling slowly up and down over big sand dunes, when all of a sudden in the midst of the sand, we came across a fair sized river on the far side of which, across a wooden bridge, stood the town of Lepzinsk, set in a bower of green. What a delightful contrast!… There were pleasant grassy meadows all around, well irrigated and with many a wild flower growing on them. The contrast to the barren country through which we had been passing made Lepzinsk look doubly beautiful. …From now on to the mountains, the rainfall is greater and the climate milder, so that vegetation becomes everywhere more luxuriant.
Day 6 (105 versts):
It took us ten hours to do 47 versts, as we had to cross a range of rocky hills that formed a kind of buttress to the snowy Ala-tau mountains. The road… followed the bottom of a narrow and stony gorge…
On arrival at the top of the pass, which was only about 4,000 feet in height, there was a glorious view of the snowy mountains, only separated from us by a narrow grassy valley.
From now onward, the road kept at the height of over 4,000 feet and we drove across beautiful grassy meadows…
Soon after mid-day we arrived at Kapal… Except for a few trees at Sergiopol and Lepzinsk, this is the first place in the 650 versts that we have traversed since leaving Semipalatinsk, where they are at all plentiful.
So there are some wonderful clues here: the arms of a sandy desert coming in from the west, the proximity of Lake Balkhash, verdant Lepzinsk in the midst of sandy dunes and first seen on the far side of a “fair sized river,” a pass at 4,000 feet in a range of rocky hills “that formed a kind of buttress to the snowy Ala-tau mountains,” and a plateau over 4,000 feet that leads on to Kapal.
To make initial sense of all this, let’s take a look at this map. This is a portion of a Soviet topographic map at 1:1 million produced in 1973.
As you can see, Kapal lies near the large northeast-trending mountain range at the bottom of the map, the Dzhungarskiy Ala-tau, which Howard-Bury calls the Ala-tau mountains.
Starting from the end and working backwards, Let’s look at the area around Kapal for a traveller arriving from the north.
This topography seems to correspond well with what Howard-Bury describes on Day 6. There’s a line of rocky hills forming “a kind of buttress to the snowy Ala-atu mountains,” and there a pass through them marked, on this Soviet map, with an elevation of 1052 metres, or 3500 feet. From the pass to Kapal the route continues to gently ascend.
The town at the foot of that 1052 m pass was marked as Джансугуров/Dzhansugurov in Russian. Now it is Жансугиров/Zhansugirov, Kazakhstan. We have reduced our task to determining the route from Sergiopol to Zhansugirov.
Let’s back up for a moment and look at rivers in the area.
There are three main rivers that feed Lake Balkash in this area. From north to south today they are called the Ayaguz (Аягуз), Lepsi (Лепсы) and Aksu (Аксу). These are three of the famous Seven Rivers that give the region its name in Kazakh (Jetyysu) and Russian (Semirechinsk).
Howard-Bury mentions following the Aksu as he leaves Sergiopol, but confusingly the Aksu is the southernmost of the three rivers we see here. It’s possible that after staying up all night for so many days became confused about which river he saw on which day. But it’s also possible that someone told him the Ayaguz was called “Aksu,” because Aksu is a very common name for rivers in Central Asia (meaning, essentially, white water or clear water).
He also refers to a Sergiopol river, which, from his reference to it entering Lake Balkhash we can assume is the Ayaguz.
We might expect a town called Lepzinsk to be on the Lepsi river, since “Lepzinsk” is essentially a Russian construction meaning “of or pertaining to Lepsi.” Surprisingly, there are three candidates for this town, and, correspondingly, three main route choices.
This town of Lepsy is absent on historical maps, but it exists today and can be found, for example, on Google maps. We’ll call this one “Low Lepzinsk” because it is lowest on the Lepsi river. Its satellite image shows that one would indeed come across this river “all of a sudden in the midst of the sand.”
This route is initially appealing because it mimics the railway corridor shown on the 1973 map. It passes close to Lake Balkhash. But, there are a few problems. The town of Lepsy is on the north side of the river, and Howard-Bury says that he sees the river “on the far side of which, across a wooden bridge, stood the town of Lepzinsk” As well, prior to getting close to Lake Balkhash, arms of desert crossing this route would come from the east.
This Lepzinsk still exists, and we can see it shown as Lepsinsk/Лепсинск on the 1973 Soviet topo. It’s much higher on the Lepsi river, near its headwaters, so we’ll call it “High Lepzinsk.”
There are a number of problems with this route as well. Overall the eastern route is too long to match the distances Howard-Bury gives. It goes nowhere near Lake Balkhash. A satellite picture indicates that rather than travelling “up and down over big sand dunes” before coming upon the Lepsi river in this area, one is in a well-vegetated region.
This town of Lepzinsk, which we’ll call Mid Lepzinsk because it is mid-way along the Lepsi river, is shown on a 1912 map of Central Asia, by Alexander Keith Johnson:
Notice he actually has two Lepzinsks. There is Mid Lepzinsk, labelled ‘Lepsinski,” and also High Lepzinsk, here labelled ‘Lepsinskaia (Lepsa).” Also, importantly, he shows the post road from Sergiopol to Kopal running through Mid Lepzinsk.
Other period maps corroborate. Here’s Edward Stanford, 1901:
Again we have the two Lepsinsks, and the same post road passing through Mid Lepzinsk.
Here’s Vivien de Saint-Martin & Schrader, Atlas Universel de Geographie, published in 1935:
They too show both Lepsinks, although High Lepzinsk is bigger, and Mid Lepzinsk is ‘Lepsinskoïe.” At this point the railway has been built to the west and the older post road is not shown
It’s also probably worth looking at the map that comes with Mountains of Heaven.
Lepzinsk is there, but it is hard to say from this map whether Mid or High Lepzinsk is intended. Looking at other maps we can see that a bearing from Kapal to Mid Lepzinsk is more north than east, whereas one to High Lepzinsk is more east than north. Without longitude lines on this map we’re making a guess, but the Lepzinsk shown seems to be north-northeast of Kopal, and therefore would be Mid Lepzinsk.
What’s confusing is that the only river shown is the Aksu, which we know to be south of the Lepsi, and in fact the author’s route is shown as going to Lake Balkhash and then up the Aksu to Lepsinsk. This seems an unlikely route choice, as if one actually went up the Aksu he would have to turn north to get to a town on the Lepsi.
An argument against Mid Lepzinsk is that it no longer exists by that name. At this site today there is a town and a crossing of the Lepsi (and it is suitably situated with sandy areas north of the river, as the satellite image below shows) but it is called Kokterek (or “Blue Tree”), Kazakhstan. I can’t find any evidence it was ever named Lepzinsk.
In favour of Mid Lepzinsk and the Central Route option is that on this route it is easy to make distances agree with the daily distances Howard-Bury gives.
So I vote that Howard-Bury’s Lepzinsk was the town today known as Kokterek, Kazakhstan, and that he took what I have shown above as the central route from Sergiopol to Kapal.
