Lone Jack

The Lone Jack mine (also known as Post-Lambert) is an inactive gold mine in the Mount Baker mining district of the U.S. state of Washington. The lode was discovered in August 1897, and is cited as sparking the Mount Baker gold rush. It lies on the east slope of Bear Mountain (a child peak of Goat Mountain) at an altitude of about 5,000 feet (1, 500 m), about 1 mile (1, 600 m) southeast of the Twin Lakes. The Lone Jack mine consists of five patented claims: Lone Jack, Whist, Lulu, Jennie, and Sidney. The mine has three adits (or portals), known as Lone Jack, Lulu, and Whist, after the veins they tap respectively. The US Mint reports 9,463 troy ounces (294.3 kg) of gold and 1,961 troy ounces (61.0 kg) of silver was recovered from the Lone Jack mine from 1897 through 1969.
