Short Communication Permafrost Creep within a Recently Deglaciated Glacier Forefield: Muragl, Swiss Alps

ABSTRACT Photogrammetric measurements of surface movement, 1981-94, on the Muragl glacier forefield (Swiss Alps) are compared to direct current resistivity surveys for the same area. At three locations isolated patches of frozen sediments were inferred, each about 10,000-20,000 m 2 in area. These we...

Description
Summary:ABSTRACT Photogrammetric measurements of surface movement, 1981-94, on the Muragl glacier forefield (Swiss Alps) are compared to direct current resistivity surveys for the same area. At three locations isolated patches of frozen sediments were inferred, each about 10,000-20,000 m 2 in area. These were deforming at surface velocities of up to 50 cm per year. The locations where creep was observed coincide well with areas where two-dimensional (2D) resistivity surveys suggest ice is present within the ground.
