We chemically analysed vegetation (willow and alder) and soil samples collected at three abandoned mercury (Hg) mines and at background sites in southwestern Alaska and compared Hg concentrations, speciation and distribution. Total Hg and methylmercury (MeHg) concentrations were higher in vegetation and soil samples from all the mine sites compared to samples from the background sites, but.

Description and interpretation of geologic materials from shotholes drilled for the Trans-Alaska Crustal Transect projectAuthors: L. Yehle, J. Odum. The Copper River Basin planning area, million acres of land, is located in the eastern portion of southcentral Alaska.

It is comprised mostly of rugged and mountainous landscape with large glaciers, wild and scenic rivers, and expansive boreal forests. The highest concentration of sites with Group C rhyolite is in the Nenana River valley, however the largest and heaviest artifacts are found to the west of the Nenana River at Lake Minchumina (Fig.

9, Fig. 10) and in the upper Kuskokwim region. This suggests the geological source of Group C material may be in the Kuskokwim Mountains (west Cited by: BETHEL, Alaska — Researchers are looking at Kuskokwim River smelt this summer as part of a mine environmental impact statement study.

Larry Moulton with Owl Ridge Natural Resources Consultants. The Ruby Creek Copper Prospect is near Kobuk, Alaska.

Historically the site has been part of the Ambler-Shungnak Mining District. Preliminary development has taken place such as surface trenching, adits, shafts, drill holes, geophysics, geochemistry, or geological mapping. Enough data has been gathered to estimate grade and tonnage.

This volume is designed to showcase the geo-technical elements of oil and gas fields of the Cook Inlet Basin of southcentral Alaska. It contains 10 chapters written by 16 authors and co-authors who have extensive experience in the basin.
