A variety of plant and animal life can be found at the monument, including many rare or unexpected living treasures.. The bluff itself is primarily Zuni Sandstone, and was part of an ancient sand dune field that covered most of the Four Corners area millions of years ago. It is capped by a darker sandstone layer called Dakota Sandstone. In addition to the geologic makeup of El Morro, the soil in the monument is often composed of a living, fragile soil crust known as cryptobiotic soil.
