Mudcracks.
Cracking mud. If you look at garden-variety mud after it has dried, you will usually see a network of cracks like the one shown in figure 1 a. The pattern results from the sequential growth of many individual cracks, and it provides a record of how each one grew. Mud is a mixture of soil and water.

mudcracks can be preserved in sedimentary rocks. These structures provide important information about depositional environments such as flow direction, climate (arid, semi-arid, or humid) and setting (e.g. fluvial, lacustrine, or marine). These structures also may indicate which direction was originally up within the rock. Tectonic forces can fold and overturn …

Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals. When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of ...In addition to fossilized mudcracks, the Moenkopi also contains other features created from flowing water and blowing sand, such as “ripple marks, and high-angle cross-bedding”.

Mudcracks (also known as mud cracks, desiccation cracks or cracked mud) are sedimentary structures formed as muddy sediment dries and contracts. Crack formation also occurs in clay-bearing soils as a result of a reduction in water content. Fresh mudcracks.
Mud Cracks are ever-enticing to the landscape photographer who explores Death Valley, especially when they're blanketed by dramatic storm clouds.
Mudcracks form when a shallow body of water (e.g., a tidal flat or pond or even a puddle), into which muddy sediments have been deposited, dries up and cracks. This happens because the clay in the upper mud layer tends to shrink on drying, and so it cracks because it occupies less space when it is dry. Figure 6: An example of mudcracksstructures.
