Glaciated Headwaters of the Little Deschutes River
It’s hard to believe that 18,000 years ago a gigantic ice cap covered the Cascade Range, up to 2,000’ thick and 170 miles long. Glaciers filled nearly every canyon with moving ice, sculpting the landscape. Much evidence of this glaciation is lost to erosion and volcanic activity, but is still well-preserved today in the headwaters of the Little Deschutes River. Here one finds a classic U-shaped canyon, 1,500’ deep with moraines and a meandering stream, easily explored on a 2-mile trail (one way) and cross-country forays.
