Twin Peaks (Alaska)

Twin Peaks are a 5,840+ ft (1,780+ m) double summit mountain located in the Chugach Mountains, in Matanuska-Susitna Borough in the U.S. state of Alaska. The mountain is situated in Chugach State Park, 27 mi (43 km) northeast of downtown Anchorage, 11 mi (18 km) south of Palmer, and 2.5 mi (4 km) north of Eklutna Lake. East Twin Peak is the higher of the two, West Twin Peak is 5,472-foot (1,668 m), and Goat Rock is a 5249+ ft crag immediately west of both.[2][3] The nearest higher peak is Pioneer Peak, 4.26 mi (7 km) to the northeast.[1] Twin Peaks' descriptive name was reported by the United States Geological Survey in 1960, but the mountain was originally known as Lach Q'a in the Denaʼina language.[4] Climbing the mountain involves scrambling with dangerous loose rock. The trailhead for the Twin Peaks Trail is located at the end of Eklutna Lake Road near the boat launch, however the trail ends far short of the summit.
