Omak Lake
Another lake, this one in north central Washington, visited during my winding drive back from Montana a couple of weeks ago.
Omak Lake has no outlet. It's a low spot in an ancient channel of the Columbia River that has been subsequently occupied by the advancing ice sheets. While the shoreline shows evidence of fluctuating water levels, I guess there isn't enough precipitation to keep up with evaporation (or subsurface drainage?). Much of the shoreline is bedrock, but there are beaches in a few spots where abundant sand and large enough waves cooperate.
Besides shaping the landscape, the glaciers left erratics picked up elsewhere. The top photo show one along the edge of the lake itself. But the main objective of this little side trip was Balance Rock, perched on a small eroded pedestal high on the slope south of the lake.
