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).
With over 3 million images in the USGS Landsat archive, choosing the best scenes can be daunting. The USGS and NASA have collaborated on global land datasets that represent examples of the best Landsat scenes from circa 1990, 2000, and 2005. NASA and the USGS have again partnered to develop the Global Land Survey 2010 (GLS2010), a new global land dataset with core acquisition dates of 2009–2011. The dataset includes Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Earth Observing Mission 1 (EO-1) images. GLS2010, and all other decadal datasets, can be downloaded at no cost at GloVis or EarthExplorer.
