Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Reserve-Resource): Large volumes of bench gravels remain, particularly at the confluence of Prichard and Eagle Creeks. Prichard Creek not dredged below Accident Gulch or above Bear Gulch.
Comment (Development): Early placer operations (1883 to 1890) a dissapointment due to deep bedrock, much water, and low grade. Attempts by Coeur d'Alene Mining Co. to mine deep placers with an hydraulic elevator from 1903 to 1909 were not successful.
Comment (Production): Grade estimated using reported recovery factor of 95 percent. Data from Yukon Gold annual reports, abstracted in Mineral Resources of the United States for the years 1917 to 1926.
Comment (Development): Murray No. 1 dredge was formerly the Yukon No. 9 dredge at Eldorado Creek, Klondike, Yukon Territory, Canada. Built in 1911 by Yuba Manufacturing Co. Dredge moved to Rogue River, Oregon in 1926.
Comment (Development): Murray dredge did not go upstream from Raven due to a shallow bar of bedrock and did not go downstream from Accident Gulch because pay gravel was too deep.
