Kusum Kanguru Tragedies, 1991. Ulric and Cathy Jessop were married in October, 1991 and decided to spend their honeymoon climbing in the Nepalese Himalaya. Their objective was the northwest ridge of Kusum Kanguru (6367 meters, 20,889 feet). They acclimatized carefully, approaching high altitude slowly and resting in their Base Camp. In mid November, they started their alpine-style ascent. On the second day, Ulric became concerned about Cathy, who was weak and lethargic. At their second bivouac, she developed symptoms of pulmonary edema. In the morning, they set off down to get her to lower altitude. Sadly, at the start of the second rappel, she collapsed and died. A second death occurred on the mountain shortly afterward. Japanese climber G. Ohta set out on December 28, 1991 to attempt a solo winter ascent on the north face of Kusum Kanguru. He disappeared after leaving Base Camp and has not been seen since.
