This landscape habitat description is based on a ground reconnaissance of the Lost Lake, West Glacier Lake, and East Glacier Lake portions of GLEES conducted during 10 days in July-September 1986 and on subsequent photo interpretation of 1:6000 scale color-infrared photographs. A ground check was conducted in July-August 1987. The classification used is a physiognomic classification of vegetation/landscape types in the study area. As such, it is based on the structural, rather than floristic, characteristics of the vegetation. Preliminary information on the floristic composition of the vegetation was obtained in the initial field reconnaissance. A detailed floristics description is presented in Chapter 3.
