JOHN DALE MENDENHALL
John Mendenhall died in Seattle July 30, 1983, three weeks after suffering a stroke. John, his wife Ruth, and other family members were vacationing in the Tetons when John was stricken on the night before a planned climb of Disappointment Peak.
An honors graduate of the California Institute of Technology (1933), John was a respected civil and structural engineer. During the World War II years, his work included design and construction of the Birmingham (Alabama) Aircraft Modification Facility. He then became Aircraft Structural Designer and later Chief Aircraft Engineer. After the war he joined the Ralph M. Parsons Company in Southern California, with whom he served for many years as Principal Project Engineer with the Petroleum and Chemical Division, and as Chief Structural Engineer. He also helped to develop standards for earthquake resistant buildings through the Structural Engineers Society of Southern California. He retired at the end of 1977, and he and Ruth moved to Seattle in 1978.
In his climbing, as in his profession, John assumed a leadership role. He began making solo ascents at the age of fourteen. His first ascent of the northeast gully of Laurel Mountain in 1930 is generally accepted as the first belayed climb in the Sierra Nevada. He climbed all through the 1930s, pioneering several early technical routes in the Sierra.
His mountaineering after 1938 centered around the Rock Climbing Section (RCS) and the Ski Mountaineers Section of the Los Angeles area Sierra Club chapter. He met his future wife, Ruth Dyar, on an RCS outing to Tahquitz Rock; they were married in 1939. John and Ruth participated in the early climbing development of Tahquitz Rock in the 1938-53 period. John led the second (first completely free) ascent of the class 5.8 Mechanic’s Route in 1938, considered by Chris Jones to be perhaps the hardest pre-World War II rock climb in the U.S. He and Ruth were frequent leaders of local Sierra Club climbing and skiing outings from 1938 until they left Pasadena in 1978.
In 1940 the Mendenhalls began a series of nine trips to the Rocky Mountains and Selkirks of Canada. They attempted Mount Confederation, which had been tried five times before. They returned in 1947 to make the first ascent. Later visits to Canada included first ascents of the north peak of Mount Lowell (1948); Mount Synge, Midway Peak, and Aiguille Peak (1952); Mount Palmer (1953); and the Northwest Ridge of Mount Temple (1957).
In his home range, the Sierra, John made hundreds of climbs, ranging from club climbs with beginners to new routes and first ascents. These included the first ascent of the North Face of Mount Williamson (1957, with Ruth) and numerous new routes on the east face of Mount Whitney, Temple Crag, the Lower Spire in Yosemite, and other difficult faces. Years of ski mountaineering included the first winter ascents of Mount Sill (1957) and Middle Palisade (1960). He also climbed in the Cascades, the Tetons, the Midwest, and the Alps.
The Mendenhalls’ two daughters, Vivian and Valerie, were born in the mid-1940’s and often climbed and skied with their parents, later becoming active mountaineers and outdoors women on their own. In a sense, however, the Mendenhall family was bigger than that—it included hundreds of beginners who learned to love and respect the mountains through John. He was a warm, patient, and intelligent mentor who never hesitated to repeat climbs with the neophytes of each succeeding generation. The affection and respect that RCS climbers felt for both John and Ruth were symbolized by the Honorary Memberships bestowed on them when they left Pasadena for Seattle. That same year, 1978, they jointly received the Sierra Club’s Francis P. Farquhar Award for “achievements in climbing, leadership, techniques, and contributions to the Club.” John also was co-author with Ruth of a climbing instruction book for beginners, which was published in its third (revised) edition in 1983 under the title The Challenge of Rock and Mountain Climbing.
John continued to be active in the mountains following their move to the Pacific Northwest. His ascents during those years included Mount Olympus and a solo ascent of Glacier Peak (1979), the West Peak of Mount Stuart (1980), Mount Index solo (1981), and the West Ridge of Forbidden Peak (1982). An AAC member from 1966, he served as Cascade Section Chairman in 1980 and was Chairman of the Nominating Committee in 1982. He was posthumously awarded the Club’s Angelo Heilprin Citation at the 1983 Annual Meeting. He was also a member of The Mountaineers.
Few climbers have equalled John’s combination of distinguished ascents and dedicated club service. That he never lost the desire to meet new friends and help others find joy in the mountains was a great gift to us all.
