A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Big Southern Butte is one of two domes rising from a sea of basalt near the center of the eastern Snake River Plain in Idaho. The butte is one of the largest volcanic domes in the world, but at 300,000 years old it is also one of the youngest.

Established in November 22, 1939, the refuge has provided a critical stopover and wintering spot for thousands of sandhill cranes, geese and other waterfowl for 75 years. Bosque del Apache's sandhill crane population has multiplied from 18 birds in the 1840s to more than 20,000 birds today. Photo by Kim Hang Dessoliers (www.sharetheexperience.org).
Trustees Release Final Study Plan for Mink Injury Determination for Hudson River Natural Resource Damage Assessment, New York

PCBs-related injury to the American mink (Mustela vison), shown here, in Upper Hudson River drainage in New York, is the focus of the newly-released, final Study Plan for Mink Injury Determination. Photo credit: Roy W. Lowe, FWS.
On July 13, 2012, the federal and State natural resource trustees released the final, publicly-reviewed “Study Plan for Mink Injury Determination -- Investigation of Mink Abundance and Density Relative to Polychlorinated Biphenyl Contamination within the Hudson River Drainage.”
The natural resource trustees in this case include:
State of New York, represented by New York Department of Environmental Conservation;
U.S. Department of Commerce, represented by National Oceanic and Atmospheric Administration; and,
U.S. Department of the Interior, represented by National Park Service and U.S. Fish and Wildlife Service.
Between 1947 and 1977, the General Electric Company released up to 1.3 million pounds of PCBs into Hudson River from two capacitor manufacturing plants, one in Hudson Falls and the other in Fort Edward. In 1984, the U.S. Environmental Protection Agency placed a 200-mile stretch of the River in New York -- from Hudson Falls to the Battery in New York City -- on the National Priorities List due to PCBs contamination.
These PCBs releases contaminated sediments in the Hudson River injuring natural resources. In 2002, the trustees finalized a strategy to determine these injuries in the publicly-reviewed “Hudson River Natural Resource Damage Assessment Plan.” This Damage Assessment Plan identified otter and mink health as an area of pertinent biological investigation. The final Study Plan for Mink Injury Determination is being undertaken pursuant to this Assessment Plan.
The objective of the Study is to estimate abundance and density of the American mink in areas within the Upper Hudson River drainage, where elevated levels of PCBs have been found, and to compare that with estimated mink abundance and density in an uncontaminated, reference river drainage, in this case, the Mohawk River. No mink will be killed, trapped or adversely affected in the Study.
Pursuant to the Damage Assessment Plan, the results of the work conducted under this Study will be peer reviewed then publicly released.
