A moving mass of frozen debris -- about 80 feet deep, 600 feet wide and a mile long -- continues to inch downhill toward the highway, both winter and summer, sweeping away everything in its path. Researchers theorize that the giant blob is sliding year-round atop a layer of water that remains a liquid despite the permafrost because it is under high pressure. It may take five to 10 years for the frozen debris lobe to reach the road at its current pace of several inches per week, but a similar formation three miles away has been clocked at 125 feet a year, almost fast enough for someone to hear the rocks move. adn/2014/06/23/3530983/as-frozen-debris-field-slides.html
