Alaska High Latitude Periglacial Geology Field Trip, June 2007
Alaska High Latitude Periglacial Geology Field Trip
#5 of 52
We visited a house, which Ken used to live in, built on an open-system pingo (ice-cored hill). Houses on permafrost often are built on pilings with an air space beneath the house to help prevent the permafrost from melting. If it melts, the ground subsides and the house sags.
