Potholes Coulee - February 21, 2015

Potholes Coulee is a fascinating geologic feature sitting on the Babcock Bench overlooking the Columbia River. It contains two parallel alcoves in the surrounding basalt separated by a 1.5 mile long rock ridge. At the head of each alcove are lakes. It was a fascinating walk for a "west sider".

"Ancient Lakes" sit at the head of the Northern Alcove.

Probably a chunk of entablature rock fallen from the walls above.

Ancient Lakes Basin from the headwall. Flood bars from the ice age floods are evident.

Dusty Lake and the wall separating it's basin from Ancient Lakes Basin.
