Rich silver ore was discovered in the mountains north of Saguache and west of Villa Grove in 1880, and the town of Bonanza sprang up that fall. The name comes from the optimistically named Bonanza mine; one of the prospectors told his friends, "It's a Bonanza, boys!" and the name stuck. In 1880-81, 40,000 people passed through the area, including former president and Civil War general U. S. Grant in Augst of 1880, drawn by rumors that Bonanza was "the new Leadville".
