Record type Site
Current site name Farewell Mineral Licks

Geographic coordinates

Geographic coordinates: -153.60885, 62.49449 (WGS84)
Relative position The Farewell Mineral Licks are located just east of a low saddle about 6 kilometers due south of Farewell Lake Lodge at an elevation of 960 feet (293 m) in the NE1/4 sec. 30, T. 28 N., R. 23 W., of the Seward Meridian. The reporter investigated the site in 1980 and 1981.

Comments on the geologic information

  • Geologic Description = The Farewell Mineral Licks are a series of three subcircular areas of dark yellow-brown soils frequently utilized as mineral licks and roll areas by buffalo (Bison bison), moose (Alces alces), and other ungulates. Each 'lick' is approximately 40 meters in diameter, and composed of distinctive yellow-brown residual soils in Quaternary drift directly overlying the active strand of the Denali-Farewell fault, a major transcurrent fault that forms an arc across central Alaska and Yukon (Bundtzen, Harris, and Gilbert, 1997). A distinct silicrete rind covers soil at the site. Dolomite fragments were recognized in one soil sample. . One soil sample taken at the Farewell Mineral licks was anomalous in copper (250 ppm), manganese (8,500 ppm), potassium (6.50 percent), and sodium (12.00 percent). The manganese may be the result of decomposed dolomite. The remaining elements may be the result of a hydrothermal plumbing system within the Denali fault system.
  • Ore Material = Iron oxides
  • Age = Quaternary, based on C14 age data summarized by Kline and Bundtzen (1986).
