A Climber's Guide to the Rocky Mountains of Canada, by J. Monroe Thorington. Revised edition (fifth printing). 12mo; xxii + 345 pages. The American Alpine Club (113 East 90th St., New York 28, N. Y.), 1953. Price $4.00, postpaid.

The fifth printing of this work evidences the demand for a manual that, for more than thirty years, has attempted to keep pace with new climbs in the Canadian Rockies. The total number of peaks included now approaches 800, while more than 650 routes are outlined. Passes, nearly 100 in number, are described and indexed. Since the revision of 1943, first ascents numbering about 50 and an equal number of new routes have been added, a considerable part of the data not appearing elsewhere in print. Additions to the introductory material include a list of the huts belonging to the Alpine Club of Canada, their locations and approaches.
