on Fuel and Engines. Mountaineering In 1907, Jones became a keen climber after receiving some tuition in Snowdonia. He went on to pioneer some of the most difficult climbs in that region, such as Paradise on Lliwedd, which he put up in 1909. His sister, Bronwen Ceridwen Jones (later Mawson), was also an accomplished climber. Together with Karl Blodig, Geoffrey Winthrop Young and the guide Josef Knubel of St Niklaus he made the first ascent of the Brouillard ridge to the summit of Mont Blanc on 9 August 1911. He thoroughly explored the Mont Blanc region and put up many new routes there. Already a member of the Committee of the Climbers' Club, in 1909 he was elected a member of the Alpine Club. The journals of both clubs contain several papers documenting his explorations. Death Both Jones and his wife were killed in an accident on their honeymoon in Switzerland, while climbing the Aiguille Rouge de Peuterey 2941m a subpeak of Aiguille Noire de Peuterey on 15 August 1912 in Italy; their guide, Julius Truffer, slipped and fell on Jones, and all three dropped nearly 1,000 feet to the Fresnay Glacier. Alpinist Paul Preuss witnessed the accident. They were buried at Courmayeur, Italy. The north summit of the Aiguille Blanche de Peuterey was named La Pointe Jones in his honour.
