Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead (Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunction with selected physicochemical data, from representative wetland types at a mining site within Salt Lake County, Utah, USA. The selected field sites included Oolitic...
The Cottage Grove Reservoir has been impacted by a point source (Black Butte Mine), where mercury mining and processing has occurred within its watershed from the 1890's to the late 1960's.

Renewed interest in the abandoned War Eagle Mine, which is
located in the center of the gold districts of central Idaho,
provided the opportunity for a detailed study of the deposit. The
goal of this study is to determine the genetic history of the deposit
with respect to regional mineralizing...
This thesis presents a mineral geography study of the
Riddle nickel development, which is the largest known nickel
deposit, and the only nickel producing mine in the United States.
The study appraises conditions for development, including
character of the deposit, spatial relationships to the market, and
the influence of government...
This thesis deals with the archaeological investigations of an 1897-1898 gold rush
structure in the town of Dyea, Alaska. Little is known about this structure (Feature 96) from the historical records. A three year project was conducted to investigate Feature 96 in order to determine the function of the structure,...
The following outline of events in the rise and fall of gold mining in southwestern
Oregon is here recorded - almost as an obituary - so that Oregonians may not entirely forget how important this industry was in building up this part of the state.
The following pictorial article on the golden years of eastern Oregon, by Miles F. Potter and Harold McCall, is an abstract from their manuscript of a forthcoming book they are calling "Golden Pebbles."
Potter is a long-time resident of eastern Oregon and an amateur historian of some of the early...
