Summary[edit]

Description

Discontinuity between Coconino Sandstone and Hermit Shale - seen while hiking down the North Kaibab trail. THe Hermit Shale undermines the sandstone, and eventually big chunks break loose and the canyon grows a little wider.

You can see the Coconino Sandstone is white and forms steep cliffs. THe Hermit Shale is red, and softer. It temds to form a slope and it undercuts the Coconino Sandstone.

My fourth day was pretty long. Since heavy weather was coming in on the North Rim, we decided that we did not want to camp a day there. So, I hiked from Bright Angel out the South Rim. Left at 130, stopped fro breaskfast at Indian Garden, and then up on the South Rim at 8 AM. Got some supplies (and a snack) and then drove over to the North Rim (about 300 km), and then hiked down the North Rim to Cottonwood Camp. It was about 27 km (17 miles).
