St Mary's Hospital Expedition to Lobsang Spire (Second Dr Peter Thexton Expedition)
Eleven members went to the Baltoro area with the scientific objective of ascertaining, using specially designed equipment, whether small blood-vessels are affected by altitude; and with the mountaineering objective of a new route on the W ridge of Lobsang Spire. The latter was successfully accomplished in (mostly) good conditions, using some fixed ropes.
