FOUR South Lakeland mountaineers have embarked upon an expedition to the rarely-visited Cordillera Quimsa Cruz range, in Bolivia.

Paul Platt, Stuart Halford, Phil Ralph and Carolyn Bailey teamed up with friends Deno Hewson and Pete Blackburn, from Wales and New Zealand, for the five-week adventure.

The mountaineers hope to attempt new climbs on previously ascended mountains, and to make the first ascents of a number of virgin peaks up to 5,500 metres high.

The trip took a year to plan, and the team is grateful for support from outdoor clothing company Montane, which supplied each climber with state-of-the-art insulated weatherproof gear; the British Mountaineering Council; the Mount Everest Foundation; Impact Development Training Group; and HL Foods.
