Apr 1, 2009 · For example, the folded Tapeats Sandstone can be seen in Carbon Canyon (Figure 3). Notice that these sandstone layers were bent 90° (a right angle), yet the rock was not fractured or broken at the hinge of the fold. Similarly, the folded Muav and Redwall Limestone layers can be seen along nearby Kwagunt Creek (Figure 4). Layers of sandstone below Earth's surface can serve as aquifers for groundwater or as a reservoir for oil and natural gas. What is Sand? To a geologist, the word "sand" in sandstone refers to the particle size of the grains in the rock, rather than the material of which it is composed.
