The elevation at the West Peak, where a radar dome currently stands, is between 2,560 feet (780 m) and 2,578 feet (786 m)[10] It stood over 2,600 feet (792 m) before the summit was flattened for the radar dome construction.[citation needed] The East Peak is at 2,571 feet (784 m).[11] The mountain is clearly visible from the city of San Francisco and the East Bay region.
