History

Rock Springs derives its name from a rock spring which flowed in the Number 6 district in the northern part of town. An account said that the spring was found by a lost Pony Express rider, but the spring station was known to Jim Bridger before 1860; the Overland Stage station was located nearby. The spring disappeared when the coal mine operations interrupted the underground flow. In the early days, Ed Cleg hauled domestic water from the sulfur spring north of Rock Springs and charged $.25 a barrel. With the mining operations, the water flow was interrupted and water was hauled from Green River and Point of Rocks.

The Scandinavian people were represented with a heavy Mormon recruitment.

The original sandstone building was designed by Mayor H.H. Edgar who chose an Italianate style. In 1907, when John Hay Sr. assumed control of the business, the location moved to C Street. RSNB owned the original building until…
