    Occurs in valleys of Dadina and Chetaslina Rivers, tributaries of Copper River, southern AK. Shown on geologic map of central Copper River region. Northernmost exposure is along south side of tributary of Dadina that drains from flanks of Snider Peak where coarse quartz-biotite schist of unit has estimated height of ft above stream level.   The large, highly glacierized Copper River basin is an important water resource for the south‐central region of Alaska. Thus, information is needed on the reaction of its hydrologic timing and streamflow volumes to historical changes in climate, in order to assess the possible impact of future by: 1.

    Maps on topographic or planimetric bases; various scales; show results of surveys using geophysical techniques, such as gravity, magnetic, seismic, or radioactivity, which reflect subsurface structures that are of economic or geologic significance. Nonetheless, records show that they mined iron ore on the Kenai Peninsula in and located gold there in In addition, the Russians were aware of copper-rich occurrences in the Copper River basin. The mining industry grew rapidly in Alaska after the United States purchased the region from Russia in

    The presence of volcanoes in a region is often a good indicator of the presence of copper because that is where basalt cavities are in abundance near the sedimentary layer of the Earth. Copper and Its Modern Applications. Copper is a mineral by definition because it is a native element on Earth. Copper is sometimes found as the free element and is present in many minerals. Important deposits are located in Canada, Chile, Germany, Italy, Peru, U.S.A., Zambia, and Zaire. The most important copper ores are the oxides, sulphides, and carbonates. One major ore, chalcopyrite (copper pyrite), CuFeS 2 accounts for about 50% of all deposits.

Located in the Late Triassic Galore Creek alkalic Cu-Au porphyry district in northwestern British Columbia, the Central Zone deposit represents the end-member of the silica-undersaturated class of alkalic porphyry systems.

The deposit is hosted by volcano-sedimentary rocks of the Middle to Upper Triassic Stuhini Group that were intruded by a syenite-monzonite complex. Copper River is the sixth book in a series featuring Cork O'Connor, sheriff of Tamarack County, Wisconsin.

Following events that happened in the prior book, Mercy Falls, we find Cork hiding out at a cabin in Michigan's Upper Peninsula/5.
