Fluted Bluffs
In the Sunlight Basin of northwestern Wyoming, Sunlight Creek has cut down through glacial moraine deposits. The glacial moraine which fills the valley between White Mountain and the mouth of Elk Creek is rather smooth and contains some Precambrian pebbles. The moraine was created by a glacier moving ustream from the Clarks Fork since no Precambrian rocks crop out further up Sunlight Creek. The moraine dammed the creek and the resulting lake formed the flat-bottomed Sunlight Basin. This view of the creek can be seen near where Forest Road 101 1B (which is a spur off Sunlight Road FR 101) turns after reaching the elevated creek bank.
