According to the Alberta Speleological Society, Arctomys is the deepest cave in North America north of Mexico at 536m length. Their rating: -523, +13. It was first looked at by cavers in 1971, and was first bottomed in 1973. Since then about one trip a year has visited the cave. The main cave is very linear, descending steeply down a seemingly enless series of free climbs and pitches. The last part of Arctomys Cave is extremely wet and the cave ends in a sump. The first sump has been freedived to a second chamber, but nobody has been beyond this point. The Straw Gallery in Arctomys Cave features an excellent collection of long soda straws and has some extremely nice flowstone.
