Two days ago, on August 8, I had a whole day in front of me and nothing pressing in need of doing. I’d just finished helping Katherine with her morning 15N injections, and at about 9:30am I decided I’d like to do a little exploring in the Alexandra Fjord area. It was a clear day, without too much wind, so I packed a lunch and some cold-weather gear (just in case) and set off to see the lower slopes of the Dome and the west side of the valley.

Rather than cross any rivers by myself, a dangerous and uncomfortable task, I planned to walk diagonally south and west across the valley away from base camp until reaching the north-flowing small river that supplies are our drinking water. This would be the same river that Katherine and I crossed on our previous excursion. Then I would follow the river upstream as it curves to the south and east, ascend the Dome to the first major bench, and traverse along the Dome at this height until I felt like coming back down and returning to camp.
Moving southwest not far from the river, I crossed a broad, nearly-level plain littered with large glacial erratics – boulders deposited by a retreating glacier. There are lots and lots of such erratics all over northern North America, remnants of the last great ice sheets some 15000 years ago. One such large erratic is the basis for the name of a brewery in Calgary, Alberta. The difference here on Ellesmere Island is that the glacier that left these erratics behind is still very much in place, and has a name, in this case the Twin glacier.
The north half of the river emerges from a canyon known as “Helm’s Deep”, descending swiftly through a channel of boulders and steep walls. I had no desire to chance the river’s current, but I wanted to see into the canyon, so I climbed a short distance alongside the rushing river before I decided "enough of this!" and scrambled up the north wall of the canyon. That scramble was probably the most tricky thing I did that day, a careful half-crawl up a steep and crumbly slope of granite boulders, soft gravel, and loose sandy soil.
My altitude where I paused to take the above photos and drink my coffee was 186 metres, according to my GPS. This number would appear again and again on my GPS screen as I traversed the bench of mixed granite and dolomite that forms this part of the Dome. I was trying to stay at roughly the same altitude, periodically turning on and checking my GPS, and while I strayed a bit, up to about 200m, down to about 170, for some reason by far the most common reading was exactly 186m.
The terrain of the bench was a mix of polar desert and wetter patches of tundra. The differences between the two ecosystems are very apparent when they are so closely juxtaposed.
I continued along the bench until I got hungry, then stopped for lunch on a prominent boulder or protrusion of bedrock. I like having a spectacular view during my meals.
I continued around to the north slope of the Dome, where the structure gradually changes from a dolomite-dominated series of benches to a granite-dominated series of vertically-running channels and shallow, steeply-pitched canyons. This granite structure is much more difficult to traverse laterally, besides which I thought I should be heading back towards camp because I was scheduled to make dinner that evening.
Below the north slope of the Dome there is a narrow strip of wet and boggy tundra, covered with a mix of sedges and black mosses. This is apparently the home of a couple of pairs of parasitic jaegers (Stercorarius parasiticus), and I met one. I spent some time verbally berating it, thinking it was a juvenile with low muscular endurance, because it repeatedly flew only a few metres, then landed, then flapped around and took off for another short flight. On later reflection, it’s more likely this was an adult faking injury to lure me away from a nest. This late in the season it seems improbable that there are any non-flying juveniles or eggs around, but this behaviour is probably an instinctive response to a potential predator.
I walked along the shoreline to the west, up towards the top of the fjord, and freaked myself out a little bit with some bearanoia: I was carrying no deterrents, not even “bear banger” firecrackers, and I knew I was in primo polar bear habitat. Fortunately, I encountered no bears.
It was very quiet, and there was little wind, perfect conditions for sound to travel far. I could hear a marine mammal periodically surfacing, so I walked down a short way and saw a pair of walruses (Odobenus rosmarus) diving and surfacing.
On my way back to base camp, I must have passed right through two jaeger territories, as I was dive-bombed repeatedly by 4 different birds, including the fake-injured dark-coloured individual I’d previously yelled at. Turnabout is fair play, I suppose.

Their attacks were quite spectacular, and I did get a bit of an adrenaline charge as these quite large birds (larger than a crow, similar to an average sea gull) wheeled in the sun and feinted towards my head. My camera was rapidly running out of battery power, so I tried to quickly escape the jaegers, but their territories are rather large and I was attacked off-and-on for about 10 minutes.
I got back to camp by about 3:00pm, more than enough time to get started on dinner. Overall, a very satisfying jaunt around the western side of the Alexandra Fjord lowlands.

OTC = Open Top Chamber.
Sorry, you spend enough time around your favourite TLA (three letter acronym) and you forget about it.
The OTCs are the structures used to raise temperatures by a few degrees over select patches of vegetation, simulating climate warming. My work at Alex Fjord mostly took place among the OTCs set up in various vegetation-type patches.
Bravo, what phrase..., a magnificent idea
