beautiful freshwater lake situated in the sierra nevada mountains. largest alpine lake in north america and the 2nd deepest lake in the united states (1,645ft. at its deepest). it falls on the border of nevada and california (about 2/3 of the shoreline is on the california side) and is an ever-popular tourist attraction. looks like a big footprint! only has only one outlet, which is the truckee river, and drains to pyramid lake in nevada.
