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. |
