The thermal regime of the active layer at the Murtèl rock glacier based on data from 2002
Abstract Active layer temperatures are presented from a rock glacier in the Swiss Alps. The data represent a full year (2002) covering parts of two very different winters. Winter/spring 2002 was very cold and dry; fall 2002 was characterized by an unusual amount of snow. Active layer temperatures ar...
