In geomorphology, an ice plateau is deiined as an ice-covered highland area whose upper surface is nearly level and whose sides slope steeply to lowlands or the ocean. A striking example of such a landform is the high ice plateau on the Juneau Icefield. This ice plateau is located in northwestern British Columbia close to the U S. border between Atlin and Juneau. Alaska. From this flat, high ice plain at an elevation oi 1875 m fall the Llewellyn, Tulsequah, and Matthes glaciers. Our most interesting observation about this ice plateau is that the present-day surface ice movement is largely independ-ent of the subglacial topology, as revealed by geophysi-cal measurements. The juneau lceiietd is the fifth-largest icefieid on the Nonh American Continent (Figure 1). This temperate to
