Once again, there are a few darker dikes, one a yard or so left of Dana's knee, and a couple more over by the river, but ALL the rock in this photo consists of basaltic dikes in roughly parallel sheets. I'm still a little baffled as to our location. This was mid- to late-morning (Followup: 10:00 AM, according to metadata in Dana's photos), so Dana's shadow is falling NW to NNW, which is more or less the same direction the river is flowing. The river itself is tightly constrained between two sharp banks- it's not a gravelly shore. And the road turns sharply to the left beyond Dana's neck and head, with an embankment that's basically devoid of vegetation. I simply can't find a good match for this spot in FlashEarth in the reach between the N/S Fork confluence and the bridge that carries the road to the south side of the river. Below is another possibility, but the shore doesn't look right, and I think we were were further downstream- that is, more of a drive- from the bridge than this seems to be.
