When we did this drive a few weeks ago in the moving truck it was too awkward to stop at the view areas, but I vowed to do so when we returned. It proves well worth the trouble – the huge San Rafael swell provides miles of beautiful skyward-thrusting Navajo sandstone. We appreciate having Anne Marie along to relate the geological facts she picked up on field trips here from Colorado College. Most of the stone was formed as an ocean bed, broken when the continent was formed, and further pushed up by a deep pocket of magma (thus the swell, or ‘anticline’).
