|Location and accuracy||Shady Creek (Gus Creek on older maps) flows into the Bettles River from the south and is labeled on modern topographic maps. The creek flows through the middle of section 23, 26, and 35, T. 32 N., R. 8 W. There is a report of prospecting in the 1900s at an unknown location along the creek and the site is arbitrarily plotted near its mouth.|
Geologic descriptionReed (1938) reported only fair prospects on what was then known as Gus Creek. He described the creek as flowing through a limestone canyon on its lower end, but widening as the bedrock changed to schist about 1/4 mile above the mouth. Kurtak and others (2002) examined Shady Creek as part of their study of the mineral resources of the Koyukuk mining district. One panned sample contained a grain of visible gold and small amounts of gold were found in analyses of their panned concentrates. They found no indications of past or recent mining along the creek or any record of claims along Shady Creek.
