Coulee Corridor Scenic Byway
Dry Falls Visitor Interpretive Center, WA

Dry Falls was created when the glacial Lake Missoula, which covered much of the area known as Western Montana, overflowed its ice dam. Evidence indicates that glaciers advanced and blocked the Clark Fork River as many as 85 miles in the last 16,000 years, creating the large lake mentioned above. The largest lake was formed 12,000-17,000 years ago, and its sudden draining produced the last and greatest flood. The Dry Falls Interpretive Center and views are outstanding.
