TitleRed Wall Limestone (Mississippian), Yavapai County, Arizona
DescriptionThe Red Wall Limestone is one of the major cliff formers in the Grand Canyon. It also crops out in other places nearby. The rock is almost entirely calcite, and the red color comes from iron staining on the rock surface. The limestone appears brown-gray when broken to reveal a fresh surface. Many different marine fossils can be found in the Redwall Limestone including brachiopods, clams, snails, corals, fish and trilobites. This sample is about 9 cm across.
