Recorder,Mining records,1870-1929.,Roughly chronological by date filed.,"General Patrick Connor\, mining entrepreneur and commander of a military unit sent to Utah in the 1860s\, and his prospector soldiers organized the Ophir Mining District in Tooele County\, Utah on 6 August 1870. Connor and his soldiers separated this southern section from the already organized Rush Valley District when they discovered a particularly promising lode in Ophir Canyon. In order to regulate mining activity and keep track of individual claims\, miners in the Ophir District elected a recorder to record notices of location and other mining documents. Each location notice confirms the validity of a claim\, states its dimensions\, and describes its location. Location notices identify each claim by a unique name\, give dates of location and recording\, and identify individuals filing the claim. In addition to location notices\, Ophir mining records include documents relating to the labor required to maintain claims.",,Public,5 microfilm reels
