Description :
This paper will review compilation of the 46-year mass balance record for the Lemon Creek Glacier (1953-1998). A comparison of topographic surface maps of the glacier made in 1957 and 1989 provides a rough determination of glacier surface elevation changes which are clearly of less precision than the compilation of annual ground data. Airborne surface profiling in 1995, and global positioning system leveling transects in 1996-1998 update the record of surface elevation changes over the past decade. The annual balance trend indicates that despite a higher mean elevation, mean annual balance has been strongly negative since 1977.
