Yosemite National Park is famous for its spectacular glacially carved landscape. Although glaciers have come and gone many times in the past, there are still two active glaciers near Yosemite's highest peaks.

Geology is the study of the Earth itself. But contrary to popular belief, geologists don't just look at rocks all day. Of course rocks are important to study, but geologists also study earthquakes, volcanoes, glaciers, and the structure...

Throughout the Sierra Nevada, high flat plateaus are found at elevations around twelve and thirteen thousand feet. These isolated sky islands are the home to unique plant communities that are found nowhere else.

The world's glaciers are shrinking at alarming rates, and many scientists believe it is due to changes in climate. Dr. Lonnie Thompson of Ohio State University and Dr. Douglas Hardy of UMass-Amherst discuss glaciers and how they...
