Cima Dome is a broad sloping upland dome, the erosional remnant of granite plutons that formed deep under the Earth's surface 180 - 80 million years ago when the Farallon Plate was being subducted beneath the North American Plate.
The Dome rises 1,500 feet (460 m) above the volcanic plain, 2,132 to 4,950 feet (650 to 1,509 m) high, and covers 70-square-mile (180 km2). Cima Dome is an extremely symmetric dome of this granitic formation type, and one of the more visible ones by being in open desert plains.

Famous quotes containing the word dome:
“The sun, the hero of every day, the impersonal old man that beams as brightly on death as on birth, came up every morning and raced across the blue dome and dipped into the sea of fire every evening. Water ran down hill and birds nested.”
—Zora Neale Hurston (18911960)
