- Alaska Glaciers Show Dramatic Melting | Geophysical InstituteColumbia Glacier in Prince William Sound and Bering Glacier in the St. Elias Mountains are two glaciers losing ice at an alarming rate: during the past decade, Columbia has shrunk by an average of about 21 feet per year along the length of the glacier; Bering has lost more than 9 feet per year.
- The Unknown Legacy of Alaska's Atomic TestsThe big daddy came in 1971. Project Cannikin was a 5-megaton explosion that inspired the formation of the group Greenpeace, a group of environmentalists from British Columbia who joined together to oppose the test. But Greenpeace and many others-including Alaska senator Mike Gravel and Congressman Nick Begich-were not able to prevent Cannikin.
- Columbia Glacier Retreating - Geophysical InstituteColumbia Glacier moves toward the sea at the rate of about one to three kilometers per year (about a mile) along its center line and roughly twice that fast along the edges where the ice is thinner. In order for the leading edge to actually move backward, therefore, the calving rate in the later months of the year must be phenomenal.
- The majesty and mystery of Alaska yellow cedarThese trees, which can live longer than 1,000 years, grow on the rainy coast from the Oregon/California border through British Columbia and as far north as Prince William Sound. The giants have in many areas died in large numbers, puzzling scientists who later came up with a non-intuitive theory of what killed them.
