Rinehart Canyon Lava Outcrop
I am heading out to a different field area, so I thought I would leave you with an interesting shot while I take a week off from the Owyhee. This is a picture of the Bogus lava outcrop at Rinehart Canyon. Here, the Bogus Rim basalt overlies a considerably thicker pile of 'older Bogus lavas'. The tapered marginal pinch of the Bogus Rim unit is hilarious in its clarity. This contrasts with the weirdness associated with the seemingly detached block surrounded by sediments along the base of the lower lavas, which have an otherwise obvious lower contact. Of equal interest is the scale-providing 'surplus' farm equipment on the slope. Thanks to Cooper for the inset detail.
