Brady Canyon is a cliff-forming gray limestone with some chert. Wood Ranch is a slope-forming pale red and gray siltstone and dolomitic sandstone. An unconformity marks the top of this formation. One of the highest, and therefore youngest, formations seen in the Grand Canyon area is the Kaibab Limestone (see 6d in figure 1).

Zion National Park is a national park of the United States located in southwestern Utah near the town of Springdale.Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park has a unique geography and a variety of life zones that allow for unusual plant and animal diversity.
Biogeology is the study of the interactions between the Earth's biosphere and the lithosphere. [1]Pyrite. Biogeology examines biotic, hydrologic, and terrestrial systems in relation to each other, to help understand the Earth's climate, oceans, and other effects on geologic systems.
The Colorado Plateau which includes the Grand Canyon is the result of broad tectonic uplift followed by river erosion. [4] When mountains rise slowly, either due to orogenic uplift or other processes (e.g., rebound after glaciation), an unusual feature known as a water gap may occur.
