Grinnell Ice Cap


Grinnell Ice Cap (Figure 1) is a thin highland ice body 0.8 km asl with eight outlet glaciers (Mercer, 1956 in Bell and Jacobs, 1997). A 1956 paper by Mercer used photographs of one of the glaciers at the Grinnell Ice Cap taken back in 1897 as evidences to show that a large decrease in volume had taken place between 1897 to 1956 (Bell and Jacobs, 1997).

In 1955, all of these glaciers were in retreat or stationary except on the south broad lobe which terminated at about 305 m asl and it was advancing over mature heath vegetation (Baird, 1955). There was superimposed ice and firn on the summit dome of Grinnell Ice Cap, but none pass 870 m asl (Baird, 1955). Precipitation is very high in this region, but coupled with warm summer temperatures and fog, there is generally a retreat pattern in in this area (Baird, 1955).

intervals 10 and 20 m. Published by NVE in1991. The map is printed in three colors(black, blue, green), with the glacier and associated glaciological features (crevasses)shown in green. NVE pioneered the use of green to depict glaciers, instead of the conventional blue, reserving blue for hydrological features (Ommanney, 2002).
