Mitten Butte. View of Mitten Butte,a typical butte temoin in Monument Valley,Arizona. A butte temoin (usually simply called butte) is an erosion feature of large sedimentary rock plains. It is formed when a resistive cap-rock is found. The sedimentary rocks around the cap-rock are more easily eroded,leaving a tower-like edifice standing after millions of years. The slopes at the bottom of the butte are composed of debris from subsequent weathering | |
