Picture A Day November 27, 2009 - Upstream at Presa Canyon
At the three-cornered junction where Seminole Canyon joins with Presa Canyon at the end of the misnamed Pressa Trail. The walls of the canyon are between 100 and 200 feet high, nearly vertical and smooth, with large multi-ton blocks of limestone spalling off to the waters below. Thousands of years of desert varnish turn the rock a dark grey, but the newer rock exposed when a block falls away is a light golden tan.
