Abstract
Dendroglaciological research was completed at Confederation Glacier in the central Coast Mountains of British Columbia, Canada. Most glaciers in this high-mountain landscape have experienced an interval of general retreat and downwasting since reaching their maximum Holocene downvalley extent during the late Little Ice Age (LIA). Our study aims to provide a late Holocene history of glacial activity in the vicinity of Confederation Glacier, as well as to develop proxy climate and mass balance records from tree-rings for the Confederation Glacier area. Field investigations in July 2008 focused on surveys of glacier forefields and proximal lateral moraine deposits located near the confluence of the Confederation and Franklin glaciers. Although these environments are now dominated by LIA landforms and deposits, older Holocene-age deposits and wood detritus overrun and buried during preceding glacial advances were discovered within stream-side incisions and collapsing lateral moraines. Our preliminary findings provide dendroglaciological evidence for the timing of the early-LIA and early Tiedemann advances. We expect that our research will contribute to more expansive reconstructions of late Holocene glacier activity in the Coast Mountains of British Columbia, and establish links between climate forcing events and late Holocene glaciological responses.
