Geologist John Clague leads a one-day tour of the Chilliwack River Valley.

SFU geologist John Clague returns for another exciting field trip, exploring the dramatic landscapes of our region.

This year, we’ll visit the Chilliwack River Valley, travelling all the way to Chilliwack Lake Provincial Park.  At various stops, we’ll observe different rock types and glacial landforms and come away with a deeper sense of the time scales during which coastal British Columbia formed and evolved.


$95/adult; $40/youth (18 yrs and under)

Price includes:

  • Bus transport
  • Geology guide Dr. John Clague
  • Naturalist guide Kelly Pearce
  • First aid support


All stops require average physical fitness and ability. There will be short walks at some locations with smooth surfaces and moderately-graded trails.

Dr. John Clague Biography

John Clague is Shrum Professor of Science at Simon Fraser University. He was educated at Occidental College (BA, 1967), the University of California Berkeley (MA, 1969), and the University of British Columbia (PhD, 1973). Clague worked as a Research Scientist with the Geological Survey of Canada from 1975 until 1998. In 1998 he accepted a faculty position in Department of Earth Sciences at Simon Fraser University, where he is currently the Canada Research Chair in Natural Hazard Research. He is Director of the Centre for Natural Hazard Research at SFU. Clague has published over 200 papers in 45 different journals on a range of earth science disciplines, including glacial geology, geomorphology, stratigraphy, sedimentology, and natural hazards, and has consulted for several private-sector firms and government agencies. His graduate students are currently conducting research on natural hazards and late Holocene climate change in western Canada.

Clague’s other principle professional interest is improving public awareness of earth science by making relevant geoscience information available to students, teachers, and the general public. He gives frequent talks to school and community groups and is regularly called on by the media to comment on a range of earth science issues. Clague has written two popular books on the geology and geologic hazards of southwest British Columbia, and a textbook on natural hazards. He is a Fellow of the Royal Society of Canada, former President of the Geological Association of Canada, and Past-President of the International Union for Quaternary Research. He is recipient of the Geological Society of America Burwell Award, the Royal Society of Canada Bancroft Award, APEGBC’s 2001 and 2005 Innovation Editorial Board Awards, the Geological Association of Canada’s (GAC) 2006 E.R.W Neale Medal, and GAC’s 2007 Logan Medal. He was the 2007-2008 Richard Jahns Distinguished Lecturer for the Geological Society of America and Association of Environmental and Engineering Geology.
