Description :
The aim of this study was to validate the existence of a lowermost altitudinal limit of mountain permafrost in Central-Eastern Norway by establishing study sites in the Sølen and Elgåhogna mountains in the Femunden area. Empirical-statistical models based on BTS and logistic regression were developed for each mountain, and validated with DC resistivity measurements. The results validate the regional west-east gradient in the altitudinal permafrost limit. Elevation is the main controlling factor for permafrost distribution on both Sølen and Elgåhogna. In addition, potential solar radiation and the surface wetness pattern were significant.
