|Location and accuracy||Munther Creek is a southeast-flowing tributary of the East Fork of the George River. The Munther Creek placer extends for about 0.7 mile along upper Munther Creek. The center of the placer is at an elevation of about 900 feet, abut 0.5 mile northeast of the center of section 30, T. 26 N., R. 41 W., of the Seward Meridian. The location is approximate.|
Geologic descriptionThe upper 0.7 mile of Munther Creek was prospected for placer gold for a number of years before World War II (Tony Gularte, oral communication, 1986). The creek drains the eastern edge of a quartz monzonite-hornfels complex at the head of Granite Pup (ID132) to the northwest (Bundtzen, Miller, and Laird, 1986; Miller and Bundtzen (1994; Miller, Bundtzen, and Gray, 2005). Fine grained placer gold was panned from several prospects along Munther Creek in the 1920s and 1930s. There may have been minor gold production during exploration (Tony Gularte, oral communication, 1986).
