Record #112726:

Geophysical investigations of an anomalous unfrozen zone, Caribou Peak, Alaska / Daniel E. Lawson, Steven A. Arcone, Charles M. Collins.

Title: Geophysical investigations of an anomalous unfrozen zone, Caribou Peak, Alaska / Daniel E. Lawson, Steven A. Arcone, Charles M. Collins.
Author(s): Lawson, Daniel E.
Arcone, Steven A.
Collins, Charles M.
Date: 1991.
In: CRREL Report. (1991.), Vol. 91-17 (1991)
Abstract: Within this watershed, continuous and discontinuous permafrost can be found, having varying slope, aspect, vegetation and elevation, thus affording opportunity to analyze importance of cover and ground conditions in controlling ground temperature and distribution of frozen ground. During drilling in April 1985, anomalous unfrozen ground was found in borehole located on north-facing slope. Impulse radar surveying of area adjacent to drill hole, and on three transects upslope, was used to determine if thaw zone could be identified, to define its distribution, and to determine its origin.
