New imagery provides evidence that meltwater played a significant role in producing the Sept. 14, 2005 massive landslide that originated from just below the summit of the 10,616 feet high Mount Steller, Alaska. The slide was one of the largest, non-earthquake generated Alaskan landslides ever observed.

A Male Spectacled Eider in Alaska
A male spectacled eider following implantation of a satellite transmitter in the Colville River delta in June 2009. After breeding numbers of spectacled eiders, a large sea duck, declined by 96 percent at a primary breeding area in Alaska, the species was listed as threatened.

Drilling into permafrost on Alaska's Arctic coast
On remote Barter Island, Alaska, Bruce Richmond (right) and Cordell Johnson drill into 500-foot-thick permafrost using a handheld drill with a 2-inch drill bit—a challenging task! It can take 3 hours to drill nearly 20 feet down.

Calyptogena spp. in Alaska
These clams (Calyptogena spp.) were discovered in about 1000 meter-deep waters off the southern tip of Alaska near a 250-meter-high cone rising from the seafloor and 10 kilometers from the Queen Charlotte-Fairweather fault.
