Published April 25, 2008
Since the mid- to late 1990s, the number and size of coal mines known as mountaintop removal mines increased dramatically in parts of Virginia, West Virginia, Pennsylvania, and Kentucky. The final step in processing this coal creates sludge that contains coal dust, sediment, and possibly heavy metals and chemicals. Mine operators contain the coal sludge in nearby valleys, behind huge earthen dams known as valley fills.

Published March 7, 2008
Each year millions of monarch butterflies migrate thousands of miles back and forth from wintering grounds in Mexico to their breeding locations in the eastern United States and Canada. In the fall, the monarchs return to just 12 forested mountaintops in central Mexico, where they form colonies in which millions of butterflies cluster on the trunks and branches of the trees. Despite the creation of protected areas and reserves, illegal logging has been steadily shrinking this unique, critical monarch habitat.

At 6:30 a.m. on May 28, 1953, Edmund Hillary and Tenzing Norgay set out from a camp high above the South Col on the Southwest Face of Mount Everest and began the ascent for which both would become famous. Fighting through snow, winding along an exposed ridgeline with drops of over 1,000 meters (3,300 feet) on either side, scrambling up steep, rocky steps, and finally climbing a sloping snowfield, the pair reached the summit at 11:30 a.m. It was the first known climb of the world’s tallest mountain.
