Location: Cascade Creek is a north tributary to Wattamuse Creek (GO021). The mouth of Cascade Creek is about 1 mile upstream from the mouth of Wattamuse Creek on Slate Creek. The lower potentially auriferous portion flows through the upper part of section 9 and the center of section 4, T. 10 S., R. 71 W. There are conflicting opinions about the extent of Wattamuse Creek. Some hold that it extends down to Slate Creek; some that it continues to the mouth of Cascade Creek (GO022) and Cascade Creek continues to Slate Creek. For this record, Wattamuse Creek continues to Slate Creek following local usage.
Geology: Cascade Creek has been explored, and drilled but apparently the only mining was near its mouth where a dredge began to work down Wattamuse Creek (GO021) (Calista Corp., 2008). The gravels are somewhat finer than on Wattamuse Creek and 8 to 10 feet deep. The drilling on Cascade Creek produced poor results. Six, 0.1 cubic yard placer samples from along about 4 miles of Cascade Creek contained a trace to 0.0017 ounce of gold per cubic yard (Fechner, 1988). Bedrock in the area includes Paleozoic and Mesozoic sedimentary and volcanic rocks, locally intruded by Upper Cretaceous to Lower Tertiary granitic rocks and Jurassic mafic/ultramafic plutonic rocks (Hoare and Coonrad, 1978).
Workings: Exploration including drilling has taken place, especially along lower Cascade Creek near its confluence with Wattamuse Creek (GO021).
Age: Quaternary.
