Layer Cake Rock (2 photos) ~

During my drive around Saguaro National Park East I stopped at all of the information kiosks. Here I learned that this striped-looking rock formation is actually called Javelina Rocks - named after its favorite inhabitant. The rocks are composed of Catalina Gneiss, ancient granite modified by heat and pressure and raised from deep in the earth. Bands of minerals in the re-melted rock create the layers of colors. Interesting!
