Snow is important to the Yosemite ecosystem because it forms a natural reservoir. The Sierra Nevada supply approximately 60 percent of the water supply for the state of California and approximately 30 to 50 percent of that water starts out as snow. Yosemite hydrologist Jim Roche explains how climate warming of 3 to 5 degrees […]
Cherry Creek is a large, swift-flowing stream in the Sierra Nevada mountain range. Watch expert whitewater kayaker Anna Wagner brave the creek’s ‘Class 5’ rapids, the most difficult type of rapids to navigate.
Concern for the future of giant sequoias has prompted a seed collection program. Researcher Dave Katz and his team from the Cornell Tree Climbing Institute venture high up in the canopy to collect seed cones for the L.A. Moran Reforestation Center, a seed bank that houses millions of seeds from conifers across California.
Yosemite is a land of giants, whether speaking of trees soaring to nearly 300 feet, or massive stone monoliths far taller than any skyscraper. Join an adventurous hang glider as he takes the plunge off a sheer rock cliff and glides like a bird over one of America’s last great wildernesses.
