Bona and Churchill, Wrangell-St. Elias Mountains. A considerable number of people have been climbing in the Bona-Churchill group. Dave Custer believes that a total of 22 climbers in five separate parties attempted Bona in May and June, of whom some 15 reached the summit. In early June, Custer’s group, consisting of John Arnason, Suzanne Lorenz, Tamar More, John Rhodes, Frank Ziegler and himself, was landed by plane on the Kutlan Glacier at 10,000 feet and camped at 12,000 and 14,500 feet. Despite doubtful weather, they climbed Bona, Churchill and the prominent bump southeast of Churchill, often called Churchill’s Chin.
