Gorphwysfa Himalayan Expedition
The Gorphwysfa Himalayan Expedition, a party of 10, mostly in their forties or fifties, led by John Jackson, attempted the S face of Mrigthuni (6850m) in the Nanda Devi Basin just E of Trisul, but were defeated at Camp 3 by bad snow conditions. Two members climbed Berthartoli S (6318m) and the Jacksons skied up to about 6,100m on Trisul.
