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. Hikers who trek to the 7,550-foot high summit are rewarded with spectacular panoramic views. Photo by Devin Englestead, BLM Upper Snake Wildlife Biologist.
First light at Bosque del Apache National Wildlife Refuge in New Mexico. 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).
DOINews: New Research Links Climate Change to Declines in Cutthroat Trout Populations
In a new study, researchers have found evidence of a linkage between climate change and the genetic decline of some species. Scientists studied populations of native westslope cutthroat trout and non-native rainbow trout in the Flathead River system in Montana and British Columbia, Canada. Findings from the research show that rainbow trout spawning and population numbers have increased due, at least in part, to climate-induced changes in the Flathead basin. This increase has led to wide expansion of hybridization with westslope cutthroat trout, causing a genetic decline in the cutthroat trout populations.
