It seems every photographer is drawn to this particular scene when they visit the canyon. It is actually very dark in the canyon, so that I didn't even realise this is the scene I was shooting. Long exposure photography brings out the light and colors unseen by humans. There's a reason thunderboomers are also called gully-washers. Most of the time this canyon is dry, like the land around it. But this canyon was cut by water -- flash floods carry tons of dirt, rocks and sticks which grind the walls. The curves carved out of the rock blend nicely with the sedimentary layers the rock is made of.
