Range:

In the Columbia River Gorge it may be found between the elevations of 100'-2500' on the Washington side of the river from about the Dallesport in the west and eastward towards Roosevelt, WA and on the Oregon side of the river, from near Celilo, OR east to Arlington, OR. It can also be found southward between Wasco, OR and Condon, OR.
