Mirror Lake is a small, seasonal lake located on Tenaya Creek in Yosemite National Park. Situated in Tenaya Canyon directly between North Dome and Half Dome, it is the last remnant of a large glacial lake that once filled most of Yosemite Valley at the end of the last Ice Age, and is close to disappearing due to sediment accumulation.
