Comments on the geologic information

  • Geologic Description = Boswell (1979) described the Cripple Creek pay channel as an ancient channel of Ester Creek (FB034) which branched from the present course of Ester Creek roughtly opposite the mouth of Ready Bullion Creek. The auriferous gravels at Cripple Creek are very deep; they are overlain by several hundred feet of barren gravel and reworked loess or so-called muck that washed into valley from the surrounding hillsides. Beds of clay several feet thick were found at various elevations. Subsequent to deposition of the gravels there had been considerable faulting and tilting that has resulted in grades of 5 to 8 percent on the surface of the gravel as well as the bedrock the gravels vary in thickness from 60 to 167 feet; these are overlain by muck that varied in thickness from 100 to 187 feet.? There was almost certainly deep, early drift mining on Cripple Creek in the early days of mining in the Fairbanks district but it was probably attributed to Ester Creek mine (FB034) or simply Ester. In the 1930, United States Smelting, Refining, and Mining Company (U.S.S.R."&"M) consolidated most of the property in Ester and Cripple Creeks, and this was one of the major centers of placer mining in the Ester area until the dredges stopped mining in the late 1960's. U.S.S.R."&"M. began extensive churn drilling on the Cripple Creek pay channel in 1933; they began stripping muck in May 1935 and barren gravel in September 1939. Dredge no. 10 started digging in August 1940 and, except for a closure during World War II, it continued on working Cripple Creek until 1964. It was the last dredge U.S.S.R."&" M. operated in the Fairbanks area and remains in its pond south of Ester.

Comments on the production information

  • Production Notes = There is no record of the amount of gold produced by dredging on Cripple Creek but it was undoubtedly large. Dredge no. 10 was a large, modern dredge when it was constructed, and it operated every year from 1940 to 1964, except for two years during World War II. Production figures are not available.

Boswell (1979) provided considerable detail on dredging operations on Cripple Creek specifically.
