You see them in Western Canada, but I’m not sure if I’ve heard of any others. Quite often they’re hidden in caves, so they’re actually underground lakes.

Where at? If there are any in YT I would love to put them on my list of places to go and see.

Not quite the Yukon, but there are some in BC: http://www.bchotsprings.com/ came up first in a quick Google search. I think that is more small ponds and such but next time you’re in a book store check out the Lonely Planet guide to Canada and look in the section on the Rockies. If it’s anywhere it will be in that book.
