The nature of the sandstone may be indicative of a desert sediment. You would expect an arkose or similar sandstone (roughly 25% feldspar and the rest quartz). You would expect there to be very little clay as the environment should be dry which would not cause the breakdown of feldspar minerals to form clay. This is not conclusive evidence but when combined with other information it all helps to build a picture of the depositional environment.
The grains in desert sandstones tend to be well sorted and rounded due to abrasion caused by wind action.
Desert sands grains tend to become stained by iron oxide minerals forming a yellow to red colour (although this does not always happen so an absence of staining does not prove the material is not a desert sandstone).
The presence of cross-bedding may be indicative of a desert formed sandstone. Wind formed (aeolian) dunes in a desert produce larger sets of cross beds than those found in water deposited (fluvial) cross bedding.
Sandstones deposited by aeolian rather than fluvial environments have a unique feature known as pinstripe laminae. These are very narrow stripes only a few grains wide consisting of finer grains than are found in grainfall laminae (which is formed by fluvial processes).
Finally if fossils are found in the rock, they should only be of land animals or land vegetation. No marine fossils should be present.
For some good examples of large scale aeolian cross bedding, please see the related link.
Common types of rocks found in desert biomes include sandstone, limestone, granite, and basalt. These rocks are often weathered and eroded due to the harsh desert conditions, leading to unique landforms such as arches, mesas, and buttes. Sedimentary rocks like sandstone are prevalent in desert regions due to their formation in ancient desert environments.
Sandstone is a clastic sedimentary rock composed of sand sized minerals, found in and near sand. Limestone is a sedimentary rock made up of the minerals calcite and aragonite, found in and near water.
When the waves erode cliffs, large pieces of rock(BOULDERS) fall off and crash down to the beach below. Pieces break off the boulders until they eventually are worn down to pebbles.. The pebbles are then eventually worn down to sand due to the force of the waves. Sandstone(sometimes known as arenite) is a clastic 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 colour, but the most common colours are tan, brown, yellow, red, gray, pink, white and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colours of sandstone have been strongly identified with certain regions. 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.Sandstone is mined by quarrying. It is sometimes found where there used to be small sea areas. It is usually formed in deserts or dry placeslike the Sahara Desert in Africa, the Arabian desert in the Middle East and the Australian desert. In the western United States and in central Australia, most sandstone is red.[1]
Sandstone is primarily made of sand-sized mineral particles (such as quartz or feldspar) that have been compacted and cemented together. It usually contains a mix of minerals, giving it variations in color and texture. Sandstone forms from the consolidation of sand deposits over time, often in environments like beaches or deserts.
No, Zion National Park does not have volcanoes within its boundaries. The park is known for its towering sandstone cliffs, slot canyons, and diverse desert landscapes, but it does not have any active or dormant volcanoes.

Sandstone and compacted dunes.
The sand does blend and form uniform colors. However, most of the 'sand' in the Painted Desert is not loose but bound to form sandstone. The different colors of the sandstone are what give the Painted Desert its name.
The mountain is likely made of sedimentary rock, such as limestone or sandstone, that formed from the accumulation and compaction of the remains of ancient ocean organisms over millions of years.

A major sandstone feature in Australia is Uluru, or Ayers Rock. It is located in the central Australian desert, and is a popular place for tourists to visit.
Ayers Rock - aka 'Uluru' - is the famous landmark in the Australian desert.
