Monashee and Selkirk Mountains. A six-man field party of the Geological Survey of Canada under my leadership was active in the Monashee and northern Selkirk mountains. Geological mapping on a scale of 1” to 4 miles was completed in the Big Bend area (Lat. 51° to 52°, Long. 118° to 119°). As in past years, back-packing trips two and three weeks long alternated with similar periods with helicopter support. In addition to ascents of several unnamed peaks, noteworthy ascents were Argonaut Mountain from the south by Jim Hylands and George Headley, and Frenchman’s Cap by Geoff Bird and me, both first ascents, and Dolphin and Pluto by the southwest ridge by Hylands and me. An attempt on Mount Trident by Scudder’s route by Ken MacKenzie, Brian Lowes and Bird came within 100 feet of the summit.
