Columnar jointing at the base of a Columbia River Basalt flow exhumed by the Scabland floods.

South of the main part of Frenchman Coulee, across the column wall.

Looking out the coulee to the southwest on a bleak winter day. Note my vehicle (outlined); in those days you could drive on the jeep roads in the coulee!

In the outwash debris below Sentinel Gap, somewhere in the Priest Rapids wildlife area. This boulder has lain there for >10^4 years now, and is somewhat worse for wear! Beer can for scale. Note how some of the original surface is preserved at the lower right.

With the raising of the water table by the Columbia Basin Project in the mid-20th century, lots of quasi-perennial streams now flow across the basin, and this one finds its way into the coulee.
