Colorado River Grand Canyon, October 2012 - joefromsf
This is Matkatamiba Canyon, which shows layered and curved Muav limestone walls.  It is challenging and fun scrambling and wading to this "patio", where the narrows open up into an amphitheater of ledges and platforms decorated with ferns and mosses.
