Observations on Pingos and Permafrost Hydrology in Schuchert Dal, N. E. Greenland.
The pingos of Schuchert Dal are found at intervals along the base of the eastern slope of this major North-East Greenland Valley. The morphology of the pingos is described. Together they illustrate a sequence of growth and disintegration which appears typical of open system pingos in this region. Of...
