The logistical efforts of Teke and Pradap Tamang of Pike Peak Trekking and a host of capable, affable support staff made this project possible. Alicia, Josh, and Dale Larson supplied support, company and field modeling duties. This research was supported by faculty start-up grants awarded by the University of Saskatchewan and the University of British Columbia and a Natural Sciences and Engineering Research Council Discovery Grant awarded to K. Larson. This guide benefited from careful readings by R. Law and R. Carosi.
