Sprague Lake Rest Stop and Somewhere East of Here

Low posting due to travel, off the grid and intense work schedule. While on the road had a stop at the Interstate 90 rest stop south of Spokane with a view of Sprague Lake. The lake is within the main Palouse Scabland glacial flood tract.
Sprague Lake and the Palouse Scabland

The lake covers only a very small width of the Palouse floodway tract. All the scab land of small mesas of basalt were shaped by the rushing flood waters. The above picture has a few mounds covered with golden colored plants. This stretch of scabland is covered with mound topography (more on a later post).

Just to the north the scab land continues, but the ponderosa forest starts softening the landscape. The highway passes by a couple of fluted hills of loess silts that were not entirely washed away by the rushing flood waters.
