Peter Thexton Memorial Expedition to Mt Kenya
In addition to making several difficult ascents in good ice conditions on the S face of Mt Kenya (Diamond Glacier-Ice Window and S face direct), this 11- man team completed a scientific project into mountain sickness based on Two Tarn Hut (4,490m), collecting data about the renin-angiotensin-aldosterene system (implicated in the genesis of acute mountain sickness) in accordance with a protocol extending over 18 days.
