At this point, we've passed by North Falls, at least the closest approach, and I took a moment to look back at the enormous space sheltered under great ledge of rock. The boundary between the contact metamorphosed sediment and overlying Columbia River Basalt is fairly evident in the upper middle, where the flash on my camera made the light/dark contrast clearer. However, it can also be picked out farther away, where the other hikers are, as a transition from lighter to darker- the colors appear to be muted greens, because most of the ambient light here is reflected off the lush vegetation out in the canyon.
