|Location and accuracy||Dictator Creek is a western tributary of Middle Fork Chandalar River, 13 to 14 miles southeast of Chandalar. The reference point is on the lower portion of the creek approximately 1 mile upstream from the mouth (sec. 10, T. 29 N., R. 3 W., of the Fairbanks Meridian). The actual location of mining along the 5-mile length of this creek is unknown. Two claims staked in 1976 are near the reference point. The location is accurate within a 1-mile radius.|
Geologic descriptionPlacer mining was reported to have occurred in 1928 and 1933 and prospecting in 1930, but no other information is available (Cobb, 1976, OFR 76-340). The area is mapped as quartz-muscovite schist; a few small outcrop areas of intercalated greenschist are in the hills above the creek (Brosgé and Reiser, 1964).
