This PDF (see page 4) has a very similar photo to the one above, with the various basalt units labeled, and a field guide going into great depth about the volcanic stratigraphy of the area.
There are numerous reasons I wouldn't live in eastern Oregon, but the views and excellent, less weathered rock exposures make it a favorite place to visit.
