Abstract
During the spring of 2002, we recovered a 220.52 m ice core and made relevant glaciological observations on Mt. Logan, Yukon Territory, Canada. This paper outlines the 2002 field studies and describes the core analyses that are planned. Meteorological measurements and stratigraphy of the core and a pit at King Col, the drill site, indicated very little summer melting at King Col. The annual snow accumulation rate at King Col between May 2001 and May 2002 was 0.6 m w. eq., which is only a third to a half of that for the previous year.
