Despite its presence below the highly studied Morrison Formation, the Chugwater receives little attention.

The most noticeable feature on a large scale is the brick-red color, caused by oxidation of iron minerals in the rock.

This color is periodically interrupted by streaks and spots of reduced iron, a light bluish-gray shade.

Though most sedimentary structures are not visible due to the gypsum interruption, there are a few examples of ripple marks and occasional crossbedding.

The Chugwater is a prime example of red beds, commonly deposited during the Permian and Triassic periods.
