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.

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).

Climate Change and Fire Regimes in the Southwest
MARCH 27; 12pm Mountain
Speaker: Julio Betancourt - U.S. Geological Survey
In the Sierra Nevada, the position of the North Pacific Jet (NPJ) strongly modulates winter hydroclimatology and, therefore, affects both tree growth and fire activity. However, there is some evidence that greater greenhouse gas-driven warming at high northern latitudes weakens the equator-to-pole temperature gradient, yielding so-called Arctic amplification and more extreme weather by altering the orientation of the NPJ. Over the last decade, the polar jet stream – the fast-flowing, high-altitude westerly air current that flows over mid and high latitudes - has experienced more north-south oriented trajectories and slower progressions, consistent with Arctic amplification. In this webinar, Dr. Julio Betancourt will discuss recent research, which uses tree-ring data from 1409 – 1990 to reconstruct how the NPJ influences tree growth and fire activity in the Sierra Nevada.
