|Location and accuracy||The Monte Cristo mine is located in the S1/2 sec. 16, T. 2 N., R. 2 E., Fairbanks Meridian. Placer mining took place on the lower mile of Monte Cristo Creek. The coordinates are the approximate center of those workings, which are about one mile north-northeast of the top of Gilmore Dome. The mine is locality 58 of Cobb (1972 [MF 410]).|
Geologic descriptionPlacer mining has taken place along the lower mile of Monte Cristo Creek. The first report of placer mining was in 1914 (Eakin, 1915, p. 233). Monte Cristo Creek drains the north side of Gilmore Dome. Bedrock in the headwaters is Cretaceous granite, and the Monte Cristo mine is now, or will be, largely consumed by the open pit of the Fort Knox gold mine (FB115), the largest gold mine in Alaska in 2001.
