Missoula Floods: Sentinel Gap 2

Sentinel Gap, Washington

This image was taken north of Sentinel Gap, looking south.  The Columbia River is barely visible in the center of the photo.  During the Ice Age Missoula Floods, Crab Creek thundered through here joining the Columbia River.  This was the western path for the waters rushing through Drumheller Channels as it was diverted by the Saddle Mountains.  The small rocks in the foreground are likely to have been carried by the rush of water as it carved out the scablands through the Drumheller Channels.
