Description

edit

Big Indian is situated three miles (4.8 km) north-northeast of theMonument Valley Tribal Park Visitor Center, onNavajo Nation land. It is an iconic landform ofMonument Valley and can be seen fromHighway 163. Precipitation runoff from this landform's slopes drains into theSan Juan Riverdrainage basin.[3]Topographic relief is significant as the summit rises 700 feet (213 meters) above the surrounding terrain in 0.25 mile (0.4 km). The nearest higher summit isSentinel Mesa, 0.62 miles (1.00 km) to the southwest.[3] This landform's toponym was officially adopted in 1964 by theUnited States Board on Geographic Names.[2] It is so named because the butte resembles the face of a native American looking south-southeast into the valley.[4] "Big Chief" and "Big Indian Butte" were alternate names that were ultimately rejected.[5]

Geology

edit

Big Indian is composed of two principal strata. The bottom layer is slope-formingOrgan Rock Shale underlaying cliff-formingDe Chelly Sandstone. The rock was deposited during thePermian period. The buttes and mesas of Monument Valley are the result of the Organ Rock Shale being more easily eroded than the overlaying sandstone.[6]
