Groundwater movement in sandstone aquifers primarily is along bedding planes, but joints and fractures provide avenues for the vertical movement of water. Sandstone aquifers can be highly productive and provide large volumes of water.The first leg of the journey went from present-day Escalante, Garfield County, to the crevasse or chute known as Hole-in-the-Rock. It was a distance of about 60 miles. Before reaching the actual point of that steep, natural crevasse, or notch, through the sandstone, the pioneers camped while scouts looked for a viable route to their destination.Wear goggles, an N95, and gloves, and work in an outdoor space to avoid breathing in dust. Place your stone on a sandbag to keep it steady as you carve. Use a hammer and chisel to chip at the stone. Chisel in the same direction as the grain of the stone, then use a file to smooth out your finished sculpture. Part 1.For lithic-rich sand and sandstone, information on the prevailing rock fragment type can be communicated by an additional adjective (Ingersoll, 1983).
