Published Tuesday-Saturday, the newspaper had previous names until 1965, when it adapted the current Daily Rocket-Miner.
The newspaper was founded in Green River in the early 1880s as the Sweetwater Gazette by the former Scotland soccer international, Robert Smith.
[3] In 1937, David G. Richardson purchased the Rocket-Miner and moved to Rock Springs from his previous residence in Newcastle, the seat of Weston County in northeastern Wyoming.
After his death, David Richardson's son, Charles (1934-2009), was elevated from general manager to publisher and president of the corporation's board of directors.
Richardson used his leadership role at the newspaper to promote economic progress in Sweetwater County, including expanded infrastructure, the establishment of a new hospital, and the expansion of Western Wyoming Community College.
