On January 28th the sun returned at last! We’ve had periods of twilight each day, but the sun has not breached the horizon since November 13th. Unfortunately, it was cloudy on Saturday…but it is getting noticeably brighter each day and we will have plenty more sunrises and sunsets before we leave at the end of February! Today is cloudy again, but technically the sun rose at 10:52am and set at 12:44pm. Unlike the South Pole, where there is only one sunset each year (see my post on that here), Summit Station gets many sunrises until May 6 when it will rise and remain above the horizon until setting again briefly on August 7th.
On the 27th the sun was very close to the horizon; a brilliant golden glow and colorful clouds hinting at its presence. On clear days this past week we have been admiring the defined earth shadow (another nice explanation of the phenomenon can be found here from Sky and Telescope) and beautiful pastel skies.

The pink layer above the darker earth shadow is called the “belt of Venus”
The new moon on the 27th meant it was a very dark night and we had a stunning view of the stars and Milky Way as well as a few curtains of aurora. Standing beneath this spread of stars with the infinite depth of the universe spread out around us is awe-inspiring.

Inside our buildings we maintain our routine. We have all but finished our fresh food and rely now on frozen, dried, or canned provisions. Everyone is growing tired and looking forward to returning to the ‘real world’ soon. Part of the issue is that we are at 10,550ft above sea level here at Summit and the physiological altitude is often much higher (we’ve seen atmospheric pressure equivalent to 12,500ft this winter). Even after initial acclimatization to the altitude it’s physically exhausting. People generally don’t sleep well up here – whether due to lack of oxygen or too much/too little day light, and after a few months it’s hard to ever feel well-rested. There’s also the mind numbing routine and isolation: We’ve been cooped up in a handful of buildings with no where else to go for months now. We all knew what we were signing up for and everyone is doing quite well, but the last 2 or 3 weeks are the hardest of any season and we’re all showing signs of Toast. There is some debate as to whether this is a “real” phenomenon – whether there is actually a medical cause (lack of T3 or vitamin D or something), but regardless it affects almost everyone in winter-over crews. Some of it is comical: short term memory degrades and you walk into a room forgetting what you were doing, then do it again 2 more times. People start a sentence or a story and forget what they’re talking about half-way through. Words become hard to remember: “Do we have any more of…umm, that thing that water goes through to make coffee?” or “Have you seen my book?…and by that I mean, my hat?” And simple math becomes especially difficult. On the flip side, frustration levels run high, tempers shorten, sleep becomes difficult, and physical energy runs low. It’s a time to remember to think before you speak, and to have extra patience for everyone who is likely feeling just as burnt out as you.
It’s also a time to be aware that we are not running on “all cylinders,” and to add to that folks are excited about post-ice plans and may not be fully present and focused on the tasks at hand. We will talk about staying present and being aware of our surroundings a lot, but we have made it through the darkest times and are down to the last month of our season now!
