This is a great place to stop for views of Grand Teton and its surrounding peaks, as well as national park plaques with information on the formation of the geological features you can see from the turnout. Try to imagine a glacier as thick as 3000 feet passing through this area 12,000 years ago. Only next to Grand Teton's 13,776-foot peak could 3000 feet of ice sound like no big deal, but these sheets of ice exerted massive power over the landscape, carving out valleys and depositing rocks and gravel in their wake. Leaving rocks, gravel, and sand behind, the glacier left the valley with a rocky floor that doesn't hold moisture well, which explains the dry conditions in the valley.
