Mount Thor, Mountain peak at Chugach State Park, United States

Mount Thor is a mountain peak in the Chugach Range of Alaska, marked by steep rock faces and formations covered in snow year-round. The harsh terrain and extreme weather conditions make it a demanding destination for experienced climbers.

Mount Thor's name was officially adopted in 1969 by the United States Board on Geographic Names, after Thor, the Norse god of thunder, because avalanches on the mountain sound like thunder. The first ascent was made in 1968 by Thomas Harrington "Harry" Bludworth, Winford Crosby "Dub" Bludworth Jr. and John Vincent "Vin" Hoeman.

The name comes from Thor, the Norse god of thunder, chosen because avalanches on the mountain sound like thunder. The toponym was officially adopted in 1969 by the United States Board on Geographic Names.
