The iconic Tuolumne Meadows, in the high Sierra, is a geological puzzle. A newly published study traces the roots of the meadows to an incident deep in time and deep below the ground.
The fire burned more than a quarter of a million acres in Yosemite and the Stanislaus National Forest. See before-and-after photos from a plot in the national forest.
National Park Services says loss of visitor spending hit some communities hard. But Pinnacles, the nation's newest national park, ducked the worst of the problems.
Ferns and new shoots from oak trees are already appearing in the ashes of the Rim Fire in Yosemite National Park. But fire ecologists say the long-term recovery of the forest could be hampered if California’s dry weather continues
A team of federal scientists is surveying areas burned by the Rim Fire to identify where the worst erosion danger is. An environmental group says restoration could cost tens of millions of dollars.
The Lyell and Maclure glaciers in Yosemite – like glaciers and ice sheets worldwide – are in rapid state of retreat. The Lyell and Maclure were presumed to be “true” glaciers – that is, thick slabs of ice dragged downhill under their own weight, scouring the land as they move – but scientists are discovering that the Maclure is deteriorating as it moves, and the Lyell is no longer moving at all.
