  • 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.

  • Permafrost geomorphological systems in a changing global climate. Special issue
  • Temporal variations in mountain permafrost creep are discussed within a regional study on rockglacier kinematics. On all investigated active rockglaciers in the Turtmann valley, a distinct acceleration of horizontal velocities has been recorded
