Scooteney Park/Othello Channels
As the floodwaters were pushed around the eastern point of the Saddle Mountains they created the Othello Channels. A hiking trail along Scootenay Reservoir provides a close-up view of the area.

When the Missoula Floods slammed into the eastern flank of the Saddle Mountains, they split around the obstruction and carved the Othello Channels -- a network of parallel flood channels that slice through the basalt south of the mountain range. The channels were created as floodwaters, unable to flow over or through the Saddle Mountains, were forced around their eastern point, concentrating into powerful streams that excavated new pathways in the Columbia River basalt. Scooteney Reservoir, situated about nine miles southeast of Othello, fills one of these flood-carved depressions and offers year-round fishing for bass, walleye, and perch. The surrounding landscape is a textbook example of the floods' ability to create complex drainage patterns in a matter of hours, with channels that look like river valleys but were carved in days rather than millennia. A hiking trail through the area follows the channels and reveals the basalt walls, scoured surfaces, and flood-deposited gravels that tell the story. The Othello Channels demonstrate that the floods were not a single monolithic torrent but a complex system of water finding its way around obstacles.

Capture roadmap

What this site looks like once Phase 1 lands.

Every site along the trail will receive the full Terrain360 capture treatment: ground-level 360° panoramas, drone aerial imagery, and photogrammetry-based 3D models that visitors can spin in their browser. This page reserves the slots; the imagery flows in as field capture completes.

Ice Age Floods National Geologic Trail

Situated about nine miles southeast of Othello, west of Highway SR-17, this body of water has a year-round open fishing season.

Smallmouth Bass, Largemouth Bass, Walleye, Bluegill sunfish, crappie, and Yellow Perch produce good action throughout the year. The lake has a large population of Lake Whitefish.

This lake is popular for ice fishing when conditions allow.

The Bureau of Reclamation campground has a developed access area with boat launch, a small dock, and toilets.

All around are signs of Ice Age floods and there effects on the landscape.
