Snow Canyon is in the hills west of St. George. To one side of the canyon are the Red Mountains, to another are the White Hills, and eroded sandstone rocks of both colors make up the cliffs on both sides of the valley. There is also a lot of black lava, which came from old volcanoes not far away. The lava, cinder cones, and lava caves are the main points of interest, but the other colorful earth formations and cliffs are beautiful. Snow Canyou is colorful, scenic and little-visited but definitely work the trip.
