Nov 17, 2021 · Sandstone is one of the most common sedimentary rocks usually located within the sedimentary basins. Sandstones are formed when sand deposits are transported by the agents of denudation such as wind, water, and thawing ice and finally deposited in the basins where they are, accumulated, compressed, and hardened. Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface.

The transition of sandstone into quartzite is a gradual process.

This trail is a popular short, steep ascent from the Back O' Beyond trailhead to the saddle points or "gaps" in Cathedral Rock. Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20-25% of all sedimentary rocks. [1] Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface.
