We visited the pinnacles shortly before sunset, which gave the light a warm quality that's difficult to capture. Photos weren't easy; there was a lot of glare looking upstream. On the other hand, I found a trick that made for some very nice shots: get the lens shaded. I think in this case I simply held my left hand in such a position as to cast a shadow on the lens. In others, I stood in the shade of foliage. In either case, shoot under the object casting the shadow. The duel composition of the tephra is apparent here, and creates the illusion of luminosity in the deeper deposits.
