Atna Peaks is an erodedstratovolcano orshield volcano in theWrangell Mountains of easternAlaska. It is located inWrangell–Saint Elias National Park about 6 miles (9.7 km) east ofMount Blackburn, the second-highestvolcano in the United States, and just south of the massiveNabesna Glacier. The mountain is almost entirely covered inglaciers, so no geological studies have been done, but published references state and the geological map shows that the mountain is an old eroded volcanic edifice.
The mountain's main summit is 13,860 feet (4,225 m), making it the second-highestthirteener (a peak between 13,000 and 13,999 feet in elevation) in Alaska. The second summit is located about 0.6 miles (0.97 km) to the east, reaching over 13,600 feet (4,100 m), and another named summit, 13,280 ft (4,048 m)Parka Peak, is about 1.6 miles (2.6 km) further east across a glacier-covered saddle. The steep rocky south faces of these three peaks form part of thecirque of theKennicott Glacier, which flows southeast over 20 mi (32 km) to just above the town ofMcCarthy.
Atna Peaks was named in 1965 by the first ascent party from theMountaineering Club of Alaska, because the "peaks are at the edge of theCopper River drainage and the old Indian name for that river was Atna."[2]
