|Location and accuracy||Jump Creek, which crosses the northeast boundary of the Bendeleben quadrangle, is a west tributary to Candle Creek. The mouth of Jump Creek on Candle Creek is in the Candle quadrangle. This location is approximate. It is locality 64 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionPlacer gold was discovered on Jump Creek by 1901 and mining took place at least up to WW II (Cobb, 1975). Candle Creek, nearby, continued to be an area of active placer operations up to recent years. Much of the mining on Jump Creek was probably along downstream parts close to Candle Creek (Cobb, 1975). Information about the nature of the placer deposit on Jump Creek has not been reported. What little bedrock is exposed in the area is part of a Lower Paleozoic metasedimentary assemblage (Till and others, 1986). A small granitic stock is exposed on the ridge south of upper Candle Creek (Till and others, 1986) and Sandvik (1956) notes that granitic rocks have been identified in the headwaters of Jump Creek and Minehaha Creek. Intermediate to felsic dikes and sills crosscutting metamorphic rocks have been exposed in placer workings along Candle Creek (BN074).
