The earliest permanent building at the town site was built in 1851 by two Messrs. Brown and Kelly. It was purchased soon after construction by O. C. Wheelock, Captain John B. Pierce, and two other unknown partners. Wheelock and his partners established a trading post, a bar, and a brothel at this site, which primarily served the troopers stationed at the fort. Near the end of the 1850s, the nearby mining camps of Hooperville and Deadwood began to disband as a result of the dwindling stores of placer gold, epidemic illness and devastating fires.
