Location and accuracy Sonickson Creek is a small south tributary of the Seventymile River (EA025). Work was conducted near the mouth of Sonickson Creek in section 8, T. 1 N., R. 29 E., of the Fairbanks Meridian. The location is accurate to within one-half mile. Sonickson Creek is locality 21 of Cobb (1972 [MF-393]), locality 55 of Eberlein and others (1977), and locality 6 of Burleigh and Lear (1994).

Geologic setting

Geologic description

The rocks in the vicinity of the mouth of Sonickson Creek are calcareous and graphitic schist that strike N 80 W and dip vertically (Prindle, 1905). Upstream, bedrock includes Paleozoic gneiss, amphibolite, schist, and greenschist, detrital rocks of Cretaceous to Pliocene age, Tertiary or Mesozoic granitic rocks, and Tertiary volcanic and shallow-intrusive rocks (Foster, 1976). Several strands of the Tintina Fault cross Sonickson Creek.
Sonickson Creek flows through a canyon with well-defined benches in the vicinity of the Seventymile River. Gravels in Sonnickson Creek contain boulders of schist, conglomerate, greenstone, and granite (Prindle, 1905). Near the mouth, the average depth to bedrock is about 8 feet. Gold is found in thin pieces, some with quartz attached (Prindle, 1905).
Some work was done on Sonickson Creek in 1903 near the mouth of the creek (Prindle, 1905). Brooks (1915) reported a little prospecting and mining with only small returns on several creeks that include Sonickson Creek. There has been placer gold production on the Seventymile River (see EA025) downstream of the mouth of Sonickson Creek.
