Grand Canyon
Grand Canyon National Park, Arizona. Marble Canyon. August 1872.
USGS Earth Science Photographic Archive digital files: hjk00854 and hjk0854a

This view is located above the mouth of Nankoweap Canyon, looking upriver, August 22, 1872. Nankoweap Canyon is located about 52 miles downstream of Lees Ferry. In this view, the Muav Limestone (Cambrian) forms a cliff and slope just above river level. The massive Redwall Limestone (Mississippian) overlies the Muav Limestone. Rocks of Devonian age (Temple Butte and Surprise Canyon formations) occur between the Redwall and Muav formations farther downstream.
