Sourdough Peak is a 6,201-foot (1,890 meter) mountain summit located at the southern edge of the Wrangell Mountains, in the U.S. state of Alaska. The peak is situated in Wrangell-St. Elias National Park and Preserve, 7 mi (11 km) east-southeast of McCarthy, on the north bank of the Nizina River. The peak is notable for a rock glacier on its south slope. The peak's name was used by early prospectors as reported in 1908 by the USGS.[3] A "sourdough" is defined as an experienced prospector or an old-timer in the western US or Canada, because they always carried sourdough starter with them. Sourdough Peak's nearest higher neighbor is Porphyry Mountain, 5.1 miles to the northwest.
