Geologic information

Identification information

Deposit ID 10307602
Record type Site
Current site name Dry Creek Cut

Geographic coordinates

Geographic coordinates: -147.47026, 63.17342 (WGS84)
Relative position The Dry Creek Cut is a truncated stream channel that formerly was a southwest-flowing tributary to lower Valdez Creek. It is the downstream extension of the Tammany Channel that has been cut off by present day Valdez Creek. The map site is about 1,000 feet south of the old Denali post office, in the NW1/4 of sec. 24, T. 20 S., R. 1 E., of the Fairbanks Meridian. This location is accurate to within 250 feet.

Comments on the geologic information

  • Geologic Description = The geology of the general area of the Dry Creek Cut is described in records HE194 and HE197. The Dry Creek Cut is the downstream portion of the Tammany paleochannel truncated by the cross-cutting younger Valdez Creek. The base of the paleochannel was higher in elevation than Valdez Creek. The cut was mined from its lower extent upstream as far as was possible without destroying the access road to Denali. The Tammany-Dry Creek paleochannel was filled with large boulders at its base and contained a very high grade placer. The descriptions of the Valdez Creek area (HE194 and HE197) that apply to the Tammany or A paleochannel also apply to the Dry Creek Cut.
  • Age = the same as Tammany paleochannel. Tammany channel is probably mid-Wisconsin in age (Reger and Bundtzen, 1990).

Economic information about the deposit and operations

Development status Past Producer

Comments on exploration

  • Status = Inactive

Mining district

District name Valdez Creek

Comments on the production information

  • Production Notes = The total production from the Dry Creek Cut is not known.

Comments on the reserve resource information

  • Reserves = No reserves remain.

Comments on the workings information

  • Workings / Exploration = The workings in this cut are impressive. In places, overburden approached 100 feet in depth. Large boulders are hand stacked adjacent to the pay channels that were mined. A telegraph pole(?) and wire are still present. The cut appears to be mined out, except for the pay gravels that remain beneath the road.
