Blackthorn Peak

Blackthorn Peak, also known as Black Thorn, is a 4,117 foot mountain summit located at the head of Glacier Bay's Geikie Inlet in Glacier Bay National Park and Preserve, in the Fairweather Range of the Saint Elias Mountains, in southeast Alaska. The mountain is situated immediately east of Geikie Glacier, 80 mi west-northwest of Juneau, and 2.5 mi north of Threesome Mountain, which is the nearest higher peak. Although modest in elevation, relief is significant since the mountain rises up from tidewater in a little over two miles. The mountain was given its descriptive name in 1896 by Harry Fielding Reid, an American geophysicist who studied glaciology in Glacier Bay. Weather permitting, Blackthorn Peak can be seen from Glacier Bay, which is a popular destination for cruise ships. The months May through June offer the most favorable weather for viewing or climbing the peak. ()
