Missoula Floods: Facing Drumheller Channels

Drumheller Channels in Distance from Top of Saddle Mountain

This image was taken from the top of Saddle Mountain (~1,300 ft elevation) looking north east over the Othello basin toward the Drumheller Channels.  Imagine a wall of water 200 – 300 feet high racing over an 8-11 mile stretch over the Drumheller Channels at over 60 miles per hour.  This was the amount of water that was released (multiple times) when the Lake Missoula glacier dam broke releasing the water over the Eastern Washington basin.  Saddle Mountain broke the onslaught of water.  Some flowed west through the Crab Creek Coulee to the Columbia River and Sentinal Gap.  The remainder rushed around the eastern edge of the Mountain and into the Pasco Basin and Lake Lewis.
