|Location and accuracy||The most prominent area of placer tailings near McLellan Creek is about 0.4 mile north-northeast of the junction of the Little McLellan and McLellan Creeks. The area is about 0.5 mile east-southeast of the center of section 32, T. 32 N., R. 2 W. The coordinates are at this location. Another area nearby is along Little McLellan Creek about 0.9 mile west of the junction of Little McLellan and McLellan Creeks. The locations are accurate.|
Other than word-of-mouth, there is little known about placer mining on Little McLellan Creek (Barker and Bundtzen, 2004). However, on their geologic map, Bundtzen and Laird (2009a, 2009b) show two areas of placer tailings near the junction of Little McLellan and McLellan Creeks. The area is covered by glacial till and outwash of two stages of the Itkillik Glaciation and by Quaternary colluvial talus deposits.
The most obvious area that is probably a placer mine is an area about 0.4 mile north-northeast of the junction of the two creeks (Bundtzen, and Laird, 2009a). Satellite imagery available on the Internet (e.g. at www.mapper.acme.com) shows an area about 500 feet long with little vegetation and signs of relatively recent mining(?) activity. The area is about 100 feet higher than McLellan Creek and if it is a placer mine, it may be a bench deposit. It is in an area of glacial till and outwash of the Itkillik II Glaciation.
Bundtzen and Laird (2009a, 2009b) show another area of placer tailings about 0.4 mile long along McLellan Creek, about 0.9 mile west of the junction of Little McLellan and McLellan Creeks. On the Internet satellite imagery, the area is heavily vegetated and placer mining is not obvious. They suggest that this placer may be derived from glacial outwash immediately below a terminal ice position of of the Itkillik II Glaciation.In early 2010, these placer tailings were on the land being explored by Goldrich Mining Company (2010) in their study of the lodes and placers of the Chandalar district.
