This is part of The Living Desert Geocache Series. The Living Desert is a wonderful place to learn more about the flora, fauna and geoscience of the world's as well as our local desert. It's situated within close proximity of the legendary San Andreas Fault.
The Living Desert is a great place to bring a family, go explore and spend the day. All caches in this series are accessible after entering the Park. Entry fee is required. If entering the hiking trails, please bring PLENTY of water, and cell phone. Watch for the usual desert critters, snakes, spiders and the like.
Sandstone is a sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray and white. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.
Because of the hardness of the individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones, for sharpening blades and other implements. Non-friable sandstone can be used to make grindstones for grinding grain.
Rock formations that are primarily composed of sandstone usually allow percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Fine-grained aquifers, such as sandstones, are more apt to filter out pollutants from the surface than are rocks with cracks and crevices, such as limestone or other rocks fractured by seismic activity.
To log this cache please email me the answer to the following question that can be found by visiting this cache location.
