I caught a look at Lake Billy Chinook in Central Oregon at a good time of day. The lake lies in canyons carved by the three rivers into earth held in place by basaltic caprock. The Confederated Tribes named the lake in honor of Billy Chinook, a member of the Wasco tribe who acted as a guide for John C. Frémont in the region of the lake. The lake is 4,000 acres in size and has 72 miles of shoreline and an average depth of 102 feet. That's the volcano Mt. Hood on the top right of the photograph. It's about 65 miles away.
