Shrinking since the early 1900s, the glaciers of Montana’s Glacier National Park are expected to continue declining over the next few decades until only insignificant lumps of ice remain.
Acquired October 22, 2008, this true-color image of Sequoia National Park shows a network of varied ecosystem, including conifer forests, river valleys, alpine vegetation, and bare rocks.
Established in 1975, the park saw fur traders nearly two centuries earlier, and it supported human inhabitants thousands of years before that. Today, almost a third of the park is water, and travel through the park is usually by boat.
