Atna Peaks, Eroded stratovolcano in Wrangell Mountains, Alaska, US

Atna Peaks is an eroded stratovolcano in the Wrangell Mountains of eastern Alaska, about 6 miles (9.7 km) east of Mount Blackburn and just south of the Nabesna Glacier. Its main summit reaches 13,860 feet (4,225 m), with a second summit over 13,600 feet (4,100 m) about 0.6 miles to the east and Parka Peak at 13,280 ft (4,048 m) further east. The mountain is almost entirely covered in glaciers, and its steep rocky south faces form part of the cirque of the Kennicott Glacier.

The stratovolcano formed as part of the volcanic activity in the Wrangell Mountains and was first summited in 1965 by members of the Mountaineering Club of Alaska. This early ascent marked the beginning of modern mountaineering exploration in this remote region.

The name comes from a Native word referring to the Copper River, whose watershed begins at these peaks. Visitors can see this geographic connection to the river valley when looking at the location of the summits.

Reaching the summit requires advanced glacier climbing skills and proper ice safety equipment to navigate the terrain. Visitors should prepare for extreme altitude, harsh weather conditions, and lengthy travel time to access this remote location.

Parka Peak, a named third summit at 13,280 ft (4,048 m), lies about 1.6 miles east of the main summit across a glacier-covered saddle. The steep rocky south faces of the three peaks form part of the cirque of the Kennicott Glacier, which flows southeast over 20 miles to just above McCarthy.
