Changes in Permafrost Distribution Produced by a Migrating River Meander in the Northern
ABSTRACT. Drill hole data from the Eagle River crossing by the Dempster Highway near the Arctic Circle have been interpreted on the basis of point bars formed by a migrating meander loop and dated by tree core ring counts. In the wake of the migrating meander loop, two waves of changes in the state...
