Nahanni Lichen Locations
Repeat photography and photogrammetry is being used to establish lichenometric dating controls for Rhizocarpon geographicum agg. lichens in the Selwyn Mountains (62°07’57” N 128° 04’05.8”W). This is about 30 km East of the mining settlement of Tungsten in Canada’s Northwest Territories. This document has a crude map and photographs that can guide workers to the marked lichens. The lichens were photographed in the summers of 2005, 2006, 2007 and 2016. If you wish to assist in this research or access the original files, please contact D. P. McCarthy at the Dept. of Earth Sciences, Brock University, St. Catharines ON. Canada.
