|Location and accuracy||Marion Creek is a large, west-flowing tributary to the Middle Fork Koyukuk River approximately 13 miles south of Sukakpak Mountain and approximately equidistant between Minnie Creek to the north and Myrtle Creek to the south. The reference point is near a prospect described by Maddren (1913) as a shaft '6 or 7 miles above the mouth' (SW1/4 sec. 14, T. 29 N., R. 11 W., of the Fairbanks Meridian); the location is accurate within a 1-mile radius.|
Geologic descriptionMaddren (1913) reported gold colors near the surface in valley gravels of Marion Creek. Initial attempts to sink shafts in the gravels of this creek proved unsuccessful, but in the winter of 1908-09 miners succeeded in sinking a shaft 26 feet to bedrock 6 or 7 miles above the mouth of the creek, where good prospects were said to have been found. According to Reed (1938) considerable prospecting was done in the 'early days,' but the gold that was found was insufficient to warrant mining. Maddren (1913), however, reported $1,000 worth of production between 1900 and 1909.
