No, NOT the One With the Green Handle

OK, I want to be clear here. In the United States, the petrol pump with the green handle is always diesel. Always! Am I right, or am I right? I thought so. And so my error was not only forgivable, but unavoidable. Unavoidable, I say! But I am getting ahead of myself.

We left Reykjavik at about 10 AM today, en route to the north, to the area around Borganes, a small town on one of the western fjords of the country. Our specific destinations were a lava cave and a couple of well-known waterfalls in the vicinity. But first we needed to fill the tank of our thirsty 4WD behemoth, a double-cab Isuzu pickup truck with an enclosed bed for our luggage.

There was a gas station just around the corner from the flat, a brand called Olío. (Notice the accent over the letter i, which gives it a long i sound.) Our vehicle requires diesel fuel, which I noticed that all the pumps offered. So I drove up to the first pump, inserted my credit card, and engaged the pump with the green handle since that is OBVIOUSLY DIESEL FUEL. I pumped about 40 liters — costing approximately 12 million dollars US — as Tim and I congratulated each other on our manly ability to pump gas in a foreign country. (By the way, for the record, petrol actually costs roughly US $9 per gallon here.) But as I hung the pump back in its cradle, my eye was drawn to an adjacent pump handle — stealthy black in color — with a tag on it that, in ominous Icelandic, read “Díesl”. By virtue of my highly advanced linguistic skills, I immediately realized that, in NASA parlance, I had screwed the proverbial pooch. In particular, I had just put about 40 liters of 95-octane petrol into a diesel vehicle. The only saving grace of the situation was that I had noticed this before we had set out on our drive and inevitably broken down in the middle of some godforsaken windswept glacial tundra, which is where it surely would have happened.

But since we were still at the petrol station, the potential catastrophe had been reduced to what Alice and I refer to in our travels as an “MSP”, which stands for “Money-Solvable Problem.” I went to the counter of the service station, where the friendly attendant called a local guy who handles this sort of thing. Said local guy, a creased, windburnt, businesslike 60-something in coveralls, showed up about 20 minutes later, siphoned out the contaminated fuel, and — because we had called him from home on a weekend — somewhat apologetically charged me an amount of money that was shockingly much even by Icelandic standards. Like I said, an MSP.

We refueled the vehicle — another 18 million dollars of “Díesl” this time — and, this particular misadventure behind us, set out on our away again. Our route to the lava cave first brought us past Borganes and its adjacent fjord, bordering a scrubby green and yellow steppe at the foot of a line of steep volcanic mountains. Despite the bleakness — it was an overcast, windy day with a smattering of rain — there was a certain stark idyllic quality to the setting, as you can see from scenes like this.

The fjord itself is broad and still, and at the time we were there the tide was out, revealing a maze of low muddy shoals. Fortunately both the wind and rain died down for long enough to allow a drone flight, during which I captured these panoramas from the air:

The bridge at lower left leads directly into Borganes. But although we are sleeping there tonight, our lava cave of interest lay about a 45 minute drive beyond it. The cave — actually a lava tube — is called Víðgelmir, which like many Icelandic place names is best pronounced whilst eating a marshmallow. It sits in the middle of a lava field at the foot of the Langjökull  glacier, which you can see here.

The cave is more than 30 meters underground with assorted ledges and overhangs, so we were first equipped with helmets with mounted flashlights. As you can see from this photo we were ready for some volcanic spelunking.

The entrance to the cave is suitably maw-like, and we picked our way along the, um, unadventurous wooden stairs and boardwalk, following our guide and listening to his lecture about the geology of the place.

We are not unfamiliar with lava tubes because of our time in Hawaii, but Víðgelmir is particularly impressive. It’s nearly a mile long and sports a variety of lava formations much more typical of a “conventional” limestone cave, e.g., stalactites and stalagmites, albeit very small ones. But its most (to me) unexpected feature is a consequence of its temperature, which hovers at just about freezing. Consequently there are a large number of crystalline stalagmite-like ice formations like these.

I found them particularly otherwordly. And indeed, if you get too close they break open and this thing that looks like a horseshoe crab jumps out and grabs your face, and you just know what’s gonna happen after that.

The cave tour lasted about an hour and a half, and we set out to our next destination, the Barnafoss and Hraunfossar waterfalls, adjacent to each other along a short looping walking path. They’re beautiful and would have made a great venue for a drone flight except that by this time the rain had started in earnest.  Hraunfossar — the name means “lava falls” — has an unusual property: its water seems to come out of nowhere. What actually happens is that the glacial melt percolates through the surrounding lava field and emerges as a line of cataracts along the river; indeed, you can actually see the water coming out of the rock. Take a look:

Iceland Barnafoss 2018-006

Barnafoss, only about 200 meters away, means “Child Falls”, named after a rather dreary local legend about them. The story goes that one day two boys, home alone while their parents went to church, got bored and decide to follow.  (The assertion that two young boys spontaneously decided to go to church on their own tells you immediately that this is a myth.)  Anyway, the legend tells that they tried to take a shortcut over a natural stone bridge that crossed the falls, but fell off the bridge and drowned. The mother of the boys then cursed the bridge, and shortly afterward it was destroyed by an earthquake. This is about as cheerful as Icelandic legends get. It must be the weather. In any case, here’s Barnafoss:

You can tell from the photos how gray the sky had gotten, and in fact it was pretty much pouring by this time. So we gawked until satisfied, then retreated to the car and returned to Borganes. Our lodgings are an AirBnb, a very pleasant two-bedroom cottage overlooking the fjord. Borganes has a population of only about 3,000 but I am happy to report that we were able to satisfy Janet’s craving for pizza: there are at least two pizzerias in town, and the one we chose was excellent.

Tomorrow: further into the frozen north!

Iceward, Ho!

In less than a week we embark on an itinerary that one could fairly call “eclectic”, even by our peripatetic standards: 10 days in Iceland, followed by 4 days each in Paris in Prague. Why those choices? We’ve been to Paris many times and love it; it’s been 8 years since we were last there, and we felt it was time to go back. Prague has been on our bucket list for some time; we know many people who have visited and come back raving around it. And Iceland seems to have gotten very trendy in the past few years, with hordes of visitors descending upon the little island, so we figured it was time to do our part. Here’s our route, just south of the Arctic Circle:

2018-08-29 20_06_49-Reykjavík, Iceland to Reykjavík, Iceland - Google Maps To give you an ideal of the scale, the island is roughly 400 km across; our driving route, the aptly-named Ring Road (marked in blue) is about 900 miles (1500 km) long. You’d think that 10 days would be more than enough time to cover that distance, but it’ll be tight: a lot of the route is slow going, and of course there is a lot to see along the way. These include geysers, glaciers, waterfalls, volcanic landscapes, glaciers, waterfalls, volcanic landscapes, glaciers, and waterfalls. And geysers.

Some fun facts about Iceland:

  • The native population is about 350,000, but the island hosts over 2 million visitors a year. In other words, if you say to a random stranger, “Þú ert með fallegt land.” (“You have a beautiful country”), the highest-probability response, spoken ver-r-r-y loudly and slowly, is, “SORRY… I… AM… FROM… OMAHA.”
  • Those entertaining-looking glyphs Þ and ð in the previous paragraph are both pronounced “th”. (Fun sub-fact: English used to have such a letter too. Its name was “thorn” — really — and it looked rather like the letter y. So on those pseudo-Olde-English signs that you see that say things like “Ye Olde Haberdashery”, the “ye” is actually the word “the“. You’re welcome.)
  • Speaking of language, modern Icelandic is essentially identical to Old Norse. This means that present-day Icelanders can easily converse with Eric the Red during seances.
  • Iceland is renowned for its impressive variety of remarkably disgusting foods, which include fermented shark and “sour ram’s testicles”. (Research topic: Are there Chinese restaurants in Iceland, and if so do they serve sweet and sour ram’s testicles?) Supposedly they also make really good ice cream and hot dogs. Guess what we’ll be eating.
  • The famous volcano whose massive eruption disrupted North Atlantic air travel in 2010 is named Eyjafjallajökull. Do not be intimidated by the word, for it is actually surprisingly easy to pronounce: just remember that it rhymes with Þeyjafjallajökull.

At an average latitude of 65° — just a hair south of the Arctic Circle — Iceland is not famed for its clement weather. And of course at that latitude, you are stuck in more or less endless night in midwinter, and get to enjoy 24-hour daylight in midsummer. But we’ll be there in September, not far off the equinox, and so neither the temperatures nor the length of the day will be particularly extreme: sunrise will be at about 6:30 AM and sunset around 8:15 PM. The daytime high temperatures will be  about 50° F (11° C), the nights several degrees cooler.

What will be cold is the water, at a cryonic 36° F (2° C). The reason this matters is that we have booked a snorkeling trip (!) at Silfra, a volcanic fissure that is essentially the boundary between the two tectonic continental plates that Iceland straddles. (Hence all the volcanoes and geysers.) It is known for its stunningly clear water, volcanic rock formations, and hypothermic tourists. I’ll report on this when it happens.

Finally, we are of course hoping to see the aurora borealis. This is definitely a crapshoot; we’re at the early end of the season for it, and as of this moment the weather forecast calls for a lot of clouds and rain, at least for the first half of the trip.. But perhaps we will get lucky.

So wish us luck, watch this space, and remember this traditional greeting: “Þjónn, ég pantaði gerjað hákarl en þetta eru hrútur“, which according to Google means, “Waiter, I ordered fermented shark but these are ram testicles.”

Yesterday, Today, and Damara

We are in Etosha National Park now, back on the grid (barely) after three days in the stark northern Damaraland region, so buckle up: this will be a long post with lots of photos. (And I should confess that the title is not quite as clever as it appears on the page because the accent is actually on the first syllable: DAMara.)

We flew – in formation! – in two small planes from Walvis Bay to Damaraland, through dust-filled skies over harsh Martian terrain reminiscent of Death Valley. In the photo below I had to stretch the contrast in Photoshop till it screamed for mercy, because what it looked like to the naked eye was a vaguely orange fog with no visible features. The sand particles here are so fine that (a) the wind carries them aloft with ease in inconceivable quantities, and (b) everything, and I mean everything, gets ultrafine grit in it, including camera equipment and bodily orifices.

One of the odd side effects of the particulate-laden atmosphere is that the intense sunlight is scattered like crazy, every solar photon getting bounced hither and yon before it reaches the ground. Which in practice means that sky is fully light a solid half hour before dawn. (I was flabbergasted one morning when I awoke to photograph the sunrise and mistakenly thought that I had misread my watch, since it was daylight and I had obviously missed it – only to see a wan orange disk creep over the distant mountains about twenty minutes later.) On the plus side, all that dust acts like a pretty effective UV blocker, so that despite the intense midday sun even I with my generally pasty complexion and vitiligo-mottled hands have not picked up any sunburn.

The wind dies down completely after sunset, however, and the dust partly settles out, which means that other than everything looking rather reddish when close to then horizon, the night sky is spectacular. Here’s the center of our Galaxy, the densest part of the Milky Way, straight overhead at about 9 PM.

That’s a 20 second time exposure, if you’re interested. Here’s another view, looking low on the horizon.

Damaraland has two types of terrain, both of them sandy. Part of it looks like the area around Kulala, i.e. rippled trackless lose sand punctuated by dunes. The more common terrain is packed sand, grey-brown hardpan strewn with sandstone and granite rubble, dotted with stunted acacia and mopane trees. There is a distant low mountain range, the Etendekas, which somply means “flat top”. If this all sounds rather survival-challenged and uninviting, it really comes down to whether you like deserts, which I do. (I could do without the grit in my ears, though.)

Our stay was it the Doro Nawas Lodge, which if you want to be a linguistic stickler should actually be written Doro !Nawas, with an exclamation point at the front of the second word. (Whoa… Microsoft word does not like that, and is complaining to me about it as I type.) It is a click sound, a “tok” made by pulling the tongue off the roof of the mouth as you say the N. There are actually four different click sounds in Damara (and San, the Bushman language), each represented in the Roman alphabet with a different punctuation mark: !, /, //, and ǂ. They sound sort of – emphasis on the sort of — like a tok, and a tcht, and a tsk, and something that I can’t even figure out a combination of letters for, let alone actually say. Even Damara children cannot pronounce them until the age of six or so. When the locals converse it sounds like they are talking while dropping marbles onto hollow wooden blocks.

The lodge appears from the outside like Mad Max’s secret fortress, a low dark wood and stone structure situated commandingly on a hilltop and ringed by cabins lower down the slope.

It is very pleasant, with few interior walls and all open to the outside. Our cabin is beautiful, a full bungalow perhaps 800 square feet (74 square m) in size with both indoor and outdoor showers and an enormous sliding glass door/window nearly 30 ft (9 m) long looking out over the desert towards the south. Everything is made of stone and dark wood like the lodge, and the cathedral ceiling looks straight up onto the underside of the thatched roof and its round rough wood beams (tree trunks, of course).

Damaraland is known for its elephants, so I might as well lay a bunch of elephant photos on you right now before I go all didactic on you.

These are desert elephants, unique to the region and a source of no little controversy. Although taxonomically and genetically identical to the “usual” African elephants, they enjoy some important and easily seen adaptations to desert life. They are noticeably smaller than their more common cousins, for one thing, with much thinner tusks and long skinny legs. (Long and skinny for an elephant, anyway.)

There is considerable controversy surrounding these animals. The national government maintains that there is no important difference between these elephants and the other 20,000 throughout the country, and that there is thus no reason not to sell expensive hunting licenses to wealthy foreigners. At the same time – speaking out of the other side of its institutional face – the selfsame government markets these permits at a premium by maintaining to those wealthy foreigners that the desert elephants are rare and special. Exactly how rare is also a point of dispute: game spotters and NGOs maintain that there are only about 120 of them; the government claims that there are 600. Nine hunting permits have already been sold, all to one wealthy and famous South African hunter Johan Louw. But the outcry over the beasts’ rarity (or not) has inhibited him from actually using them. (Karma is a Bitch Department: Louw was injured by an elephant, and his client killed, by an elephant during a hunting party in a different part of the country several months ago.

The locals have mixed feelings about all this. Elephants bring a lot of tourism to the country, but the government is so corrupt that most of those dollars do not flow down to the grass roots to fund infrastructure, schools, etc. What does happen at the village level is that the elephants destroy things, notably water wells. So the corruption problem is going to have to be alleviated before conservation efforts get the necessary amount of support at the local level.

We visited one of those villages, a Damara farming community where the village elders, who with the entire population of a few hundred, had been relocated to this patch of desert by apartheid policies in 1974.  Here’s the village, which comprises a couple of hundred people, a few goats, and some garden plots. Only one resident is brave enough to raise a garden of substantial size. Why? Well, you know how hard it is to keep pesky deer and rabbits from eating your vegetable garden? And how the bigger the garden, the bigger the problem? Now replace the deer and rabbits with elephants. A chicken-wire fence will not do the job.

You may conclude from the photo above that the village is not the most inviting place to live, and I can state with confidence that if I and my family were forcibly relocated there that we would not survive a week. (“Satya! STAY AWAY FROM THAT ELEPH… oh jeez….”) However, by their own standards the village is doing OK, and the elders at least stated that they were happy there.

They seemed to be receiving a fair amount of government support, in the form of financial subsidies, well boreholes, and even a very rare kindergarten school. This seems to be at least one case where the system is working more or less as it is supposed to, and these two ladies claimed to be very supportive of the desert elephant conservation efforts. (In answer to that question, they responded: “We like the elephants. You’re here because they’re here.”)

In contrast to this village, with real people living their daily hardscrabble lives, we also visited the Damara Living Museum, which if you are an American reading this, you may think of as Naked Colonial Williamsburg. There, local Damara tribespeople don traditional close and demonstrate dances and assorted skills (building a fire, preparing an animal hide, that sort of thing).

It’s hard to know how to feel about this. If I were part of a Jewish congregation making a living by demonstrating bar mitzvahs or seders for tourists I would not be too crazy about it, but Lloyd maintains that these Damara are OK with this, in part because it helps keep the ancient skills and traditions alive. (However, for the record, if I am one of those hypothetical Jewish congregants I am drawing the line at circumcision.)

Relocation aside, desert tribes have lived in this area for a long time. They’ve got the wall art to prove it, in this case petroglyphs on sandstone much as one finds in the American Southwest and in Australia.

Unlike petroglyphs elsewhere, however, these are impossible to date with any certainty. The analogous carvings in the USA and Australia are usually dated by organic or carbon dating analysis of any pigments in the drawings or remains of campfires. But there are no campfire remnants here, nor pigments; they are scratched into the rock. And the utter lack of rainfall means that the carvings erode slowly and unpredictably. As a result, the best that anyone can say is that the petroglyphs are between 2,000 and 6,000, which is an unsatisfyingly wide range.

You can probably infer from the pictures that the geology of this area is very similar to that of the American Southwest, and you’re right. Here is a shot that validates that sense.

The area even boasts a number of petrified forests, both privately and government owned, and they look like, well, petrified forests everywhere. We visited the government-run one, whose centerpiece is a log about 2 ft in diameter and roughly 200 ft (60 m) long, sort of a skinny redwood collapsed onto its side.

Possibly the stars of the local geology are the so-called Organ Pipes, vertical columns of a mélange of minerals, compressed by volcanic pressures into polygonal cross sections.

What this region has that is truly unique, however, is a particular plant, the Welwitschia Mirabilis, a.k.a. the national plant of Namibia. It even appears on the flag.

It’s your typically curious desert plant, that not only requires little water but actually requires it: dump a pitcher of water on it and you’ll kill it. The root system only goes down about a foot or so (30 cm) and is a big bulbous thing for water storage.  It’s very slow growing and long-lived — this one is decades old, the leaves thick and leathery.

We left Damara this morning and, as I type this, have already had a game-rich day in Etosha, further to the north. More about that when I get a chance, but I will leave you with our farewell visitor to our cabin in Doro !Nawas this morning, sitting on a fence post about four feet away from me. I have a nice photo of him, but I think Alice’s little watercolor captures the moment nicely.
