Leigh Canyon is located in Grand Teton National Park, in the U. S. state of Wyoming. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago, leaving behind a U-shaped valley. Leigh Canyon is approximately long and is flanked by Mount Moran and Thor Peak to the north and Mount Woodring to the south. The canyon outlet is at Leigh Lake and at the head of the canyon lies Mink Lake.
