The sly humor really makes this document readable. I love the list of what the base does NOT have, including "spiders or snakes!"
No there are not giant arctic worms here at Thule. What happens is the sun melts the top layer of snow and ice during the day, and then freezes during the night. You can’t tell from looking whether there’s snow, water, ground, or just open space underneath it, or how high it is. Sticking to the roadways is your best option.
The bit about giant worms is a dune reference.
I also like how they have both reliable and undependable communications:
Even though we have reliable telecommunications throughout the base, these services are limited and sometimes undependable due to connections.
They are so far north than the Northern Lights are to the south! :)
