Dale Portman is a retired park warden who spent nearly 30 years working for the warden service, often involved with backcountry travel, mountain rescue and avalanche control work in Jasper, Banff, Yoho, Glacier and Revelstoke national parks. He and his wife, Kathy Calvert, live in Cochrane, Alberta, and head to the mountains as often as possible. Dale has written three books about his experiences working in the mountains of western Canada: Riding on the Wild Side: Tales of Adventure in the Canadian West, Rescue Dogs: Crime and Rescue Canines in the Canadian Rockies and Guardians of the Peaks: Mountain Rescue in the Canadian Rockies and Columbia Mountains , the latter co-written with Kathy. Besides seeing new cultures in foreign lands, Dale's greatest love is for extended trips to remote parts of the Canadian Rockies, by skis, on foot or on horseback leading a couple of pack horses.
