Bonanza Peak, a 6,983-foot mountain in Alaska’s Wrangell Mountains near Kennecott and McCarthy, became a landmark of the region’s copper boom after the Bonanza ore body was discovered in August 1900. Stephen Birch confirmed the Bonanza Mine as the world’s richest known concentration of copper, and five mines on and around the mountain yielded vast amounts of copper and silver from 1909 to 1938, generating enormous revenue and profit for Kennecott. The mountain’s exceptional wealth came from unusually rich deposits formed where Chitistone limestone meets Nikolai greenstone. Today it is remembered both for its dramatic subarctic setting and its mining history.
