We’ve joined scientists atop a frozen debris lobe, a slow-moving landslide in permafrost. They say we’re ‘on the back of the beast’. In the heavy rain and among fog-shrouded mountains, the scientists are making these uphill treks to record how temperature, water pressure, and local geological properties determine the slope movement of the massive lobes.

Marie Gilbert for UAF Cornerstone – As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates, according to survey results from 41 international scientists published in the Nov. 30 issue of the journal Nature.

The latest examples are the stone footprints of two different dinosaurs near the tiny settlement of Chisana in the Wrangell Mountains. Fiorillo, a dinosaur hunter with the Museum of Nature and Science in Dallas, recently wrote of the foot […]
