Fish Lake is a shallow thermokarst lake located in the Old Crow Flats, a region traditionally used by the Vuntut Gwitchin for fishing. The site offers a freshwater snorkeling experience with depths ranging from 1 to 5 metres, averaging 3 metres. Conditions are generally mild, though the water is cold, requiring appropriate thermal protection. Access is via the shore. The environment is suitable for intermediate snorkelers interested in observing the lake's physical characteristics and its freshwater habitat. Due to the nature of the site, visitors should be prepared for cold water conditions while exploring this shallow, still-water environment.

Old Crow River in Canada is a subarctic freshwater site primarily used for underwater fossil prospecting. Snorkellers explore shallow point bars where Pleistocene fossils, including mammoth, horse, and bison remains, are frequently found on the river bottom. This site is suitable for advanced snorkellers only, as conditions include strong currents, low visibility, and very cold water temperatures. Access is via shore entry. Due to the subarctic climate, water temperatures remain cold throughout the year, with the most manageable conditions occurring during the short summer season.
