Mount Washington is a shield volcano in the Cascade Range of Oregon. The mountain dates to the Late Pleistocene. However, it does have a line of basaltic andesite spatter cones on its northeast flank, which are approximately 1,330 years old according to carbon dating. The main peak is a volcanic plug that was heavily eroded by glaciers in the last ice age.
