Isa Lake is an interesting lake. It straddles the continental divide in Yellowstone National Park. One half is on one side of the divide (and road) and the other is on the other side. What makes it even more interesting is that this means half the lake drains to the east, and half to the west, of the continental divide. The east drains to the west and the west to the east. Confused yet? Even better, if you are a bacterium, let’s say a bacterium with an infinitely long lifespan and the ambition of Lewis and Clark, this would be your Northwest Passage.
