One image portrays an overflow drainage pipe connected to the St. Thomas pond near Bunkerville, Nevada.

The Fred Houghton Papers (1909-1998) consist of Houghton’s legal and personal files on his Blue Chip Ranch property in Las Vegas, Nevada. The materials include legal cases, maps, reports, and correspondence concerning water access on the property, and his work with the Las Vegas Well Users Association, which primarily contains correspondence in conjunction with Las Vegas's water politics. The collection also contains court cases during the 1930s when Houghton worked as a lawyer in Chicago, Illinois, as well as legal files for his time as a public defender for the State of California. The personal files in the collection primarily consist of correspondence, banking records, diaries, and notebooks.

Collection consists of an original manuscript, "Geology and Ore-Deposition at Tonopah, Nevada" by Josiah Edward Spurr (1870-1950) with hand-drawn diagrams, and letters discussing the donation of the manuscript. The manuscript, which was published in the journal Economic Geology in 1915, is a geological description of the Tonopah mining area; the Tonopah Mining Company is mentioned frequently. It is undated, but the publication date suggests it was written approximately 1913-1915.
