Location and accuracy Lost Creek drains southwest into the Salcha River. The creek is roughly 19 miles long and has several tributaries. The Alaska Division of Mining Kardex file system reports placer mining on Lost Creek, but it is unclear where mining activity took place. The approximate midpoint of the creek is in NW1/4NE1/4 section 17, T. 1 S., R. 17 E., of the Fairbanks Meridian. The creek can be accessed by the Salcha River. It was not identified as a separate location by Cobb (1972; MF-388) or by Cobb and Eberlein (1980).

Geologic setting

Geologic description

Weber and others (1978) described the bedrock in the region as primarily quartzite, phyllite, schist, gneiss, slate, and marble. Numerous Tertiary and Cretaceous granodiorite to quartz monzonite igneous bodies intrude the area. The Alaska Division of Mining Kardex file system records active claims on Lost Creek as recent as 1980. It is unclear how much gold has been produced from Lost Creek.
