DENDROGLACIOLOGICAL DATING OF A LITTLE ICE-AGE GLACIAL ADVANCE AT MOVING GLACIER, VANCOUVER-ISLAND, BRITISH-COLUMBIA

Dendrochronological investigations at Moving Glacier provide the first calendar-dating of a Little Ice Age glacier advance on Vancouver Isla nd. In 1931, Moving Glacier was within 30 to 50 m of a distinct trimli ne and terminal moraine marking its maximum Little Ice Age extent. A r econnaissance of the site in 1993 revealed the presence of sheared in situ stumps and detrital trunks inside the 1931 ice limit. Sampling in 1994 showed the site was covered by a mature subalpine forest prior t o the glacial advance which overrode the site after 1718 A.D. Followin g this period or expansion, which saw Moving Glacier expand to its max imum Little Ice Age position after 1818 A.D., the glacier apparently e xperienced only minimal retreat prior to first being photographed in 1 931.
