Sentinel Peak is a 4,355-foot (1,327-meter) mountain summit located at the head of Glacier Bay's Queen Inlet in Glacier Bay National Park and Preserve, in the Alsek Ranges of the Saint Elias Mountains, in southeast Alaska. The mountain is situated immediately southwest of Carroll Glacier, 87 mi (140 km) northwest of Juneau, and 7.44 mi (12 km) east of Mount Abdallah. Although modest in elevation, relief is significant since the mountain rises up from tidewater in less than two miles. The mountain was named in 1892 by Harry Fielding Reid, an American geophysicist, who studied glaciology in Glacier Bay. He so named it because Carroll Glacier is guarded by Sentinel Peak, and a sentinel is a guard whose job is to stand and keep watch. Weather permitting, Sentinel Peak can be seen from Glacier
