Henry Constock was born in Ontario, Canada, in 1820. He’s famous for one of the richest gold and silver strikes in history, giving his name to the ore deposit. Constock drifted as a trapper until he settled in the western Great Basin’s Gold Canyon. There he mined placer sands. On June 8, 1859 Constock encountered Patrick McLaughlin and O’Riley working a rich outcropping to the north, which he asserted he owned. They called this the Constock Lode. Eventually he sold his share of the claim. He moved to Bozeman, MT in 1870.
