Abstract

The Little Ice Age behaviour of glaciers in the central British Columbia Coast Mountains was described by conducting lichenometric surveys of Rhizocarpon spp. found on recently deposited moraines in the Kitimat and Pacific ranges. The timing of these moraine-building episodes corresponds closely to the intervals of glacier expansion recorded in complementary studies in the region. These findings indicate that most glaciers in the region reached their maximum downvalley Little Ice Age extent prior to 1780 ad, and suggest that climate forcing likely contributed to regionally synchronous glacier fluctuations
