Alpha Falls




Alpha Falls, also known as Gardiner Falls, is the mouth of the valley leading from Alpha Pass. The falls most likely formed after lake drainage through Alpha Pass was complete. Later lake drainage eroded the main gorge to its present level, leaving the valley above the falls "hanging" along the gorge wall. Many waterfalls along the walls of the gorge are at the mouths of similar "hanging valleys."

Almost none of the Homewood Sandstone has been eroded at the top of the falls, suggesting that the valley has never had much flow since glacial lake drainage ceased.
