International Conference on Sediment and Geochemical Budgets in Geomorphology to honour Professor Olav Slaymaker
June 27th - 30th, 2004
The University of British Columbia, Vancouver, Canada
Field Trip #1 - Lillooet River Basin,
led by Olav Slaymaker, Michael Bovis and Erik Schiefer
Date: Sunday, June 27th
Field trip is now full.
Thirty five years ago, we started work on the sediment budget of Lillooet River basin, a 3,850 km2 basin containing 400 km2 of glaciers and ice fields and an unusually active sediment source in the form of the Meager Creek volcanic complex. This complex consists of early to mid Pleistocene dacite and rhyolitic lava and pyroclastic deposits which have undergone hydrothermal alteration. The valley experienced extensive river training under the direction of the Water Development Branch of the Prairie Farm Rehabilitation Act from 1946-1951, a process which steepened and straightened the river above Lillooet Lake and lowered the outlet of Lillooet Lake by 2.5 metres. Gradual growth of population in the village of Pemberton since its incorporation in 1966 contrasted with the rapid growth of the Mount Currie Reserve, the home of the most westerly of the Interior Salish people, located directly on the Lillooet River delta. More recently, since about 1995, Pemberton has become a bedroom community, serving the needs of Whistler, whose prominence as an international skiing destination has made housing prohibitively expensive. Consequently, heavy investment in building of homes on the Lillooet River floodplain is now evident. Research in the northern half of the basin has been directed by Michael Bovis; that in the southern half by Olav Slaymaker.
