Travel to Yellowstone Lake

At 7,732 feet in the air, Yellowstone Lake is the largest freshwater lake above 7,000 feet in all of North America. This large, crystalline lake is a hotbed of geothermal activity, and in addition to housing geyser basins on its shores also contains underwater hot springs. The locations of these covered springs are easily seen during the winter, when the boiling water that pours out of them melts holes into the otherwise thick sheet of ice covering the lakebed.
