much lower than water discharge released from glaciers (Krainer and Mostler, 2002).
According to their functionality, active rock glaciers are those that are moving at the
present time. Active rock glaciers moving at rates of 22 cm/yr have been recently reported
in the Pyrenees (Spain) (Serrano and Agudo, 1998). Inactive rock glaciers do not show
movement today but still contain frozen material (Barsch, 1988). Generally, the initial
