Hamish MacInnes.

After a long and remarkable life, Hamish MacInnes died on Sunday at the age of 90. We owe a huge amount of our enjoyment of mountaineering to Hamish. His contribution to mountain culture was immense, his work on mountain rescue was groundbreaking, his personal climbing was cutting edge and his development of climbing techniques made profound changes to how we go climbing. ​It's no exaggeration to say that the modern ice climbing technique of using two ice axes and steeply inclined picks was developed in Lochaber and Hamish MacInnes was at the forefront of this. His “Terrordactyl” ice axes led the way in metal shafted ice axes with inclined picks. We still use this technique today.

Way back in 1957, Hamish made the first ascent of Zero Gully on Ben Nevis. In the years following his ascent, several others tried the climb and there were some fatal accidents, often caused by wooden shafted ice axes breaking in a fall. Hamish was driven to engineer the first metal shafted ice axes, which he worked on in his workshop in Glencoe.

In the winter of 1960 Jimmy Marshall and Robin Smith completed the most significant week of climbing ever achieved in Scotland. Orion Direct, Smith's Route, Minus Two Gully and the first single day and free ascent of Point Five Gully were amongst the seven climbs they completed on consecutive days. All of this was achieved with a single ice axe each and crampons with no front points.

Ten years later in 1970 Yvon Chouinard made a brief visit which was to trigger a change that would revolutionise winter climbing. Using prototype curved ice hammers he made some very fast ascents demonstrating how to climb ice by direct aid, hanging off the pick itself embedded in the ice. Comparing techniques with Hamish MacInnes, John Cunningham and others, modern ice climbing was born.

​​That year Hamish MacInnes developed "The Terrordactyl", a short, all metal ice tool with a steeply dropped pick. The "Terror" and Chouinard's ice hammer dominated the forefront of international ice climbing for several years. Eventually these two designs were combined to create the banana pick which is still the basis for modern ice tool design. Fifty years later, we are still using the same techniques and style of picks.

Hamish had a hand in setting up Glencoe Mountain Rescue Team, Search and Rescue Dogs Association and Scottish Avalanche Information Service. His rescue stretchers are still the favourite design of many teams in the UK. He ran the Glencoe School of Winter Climbing, making many first ascents of climbs in doing so.

We owe a lot to Hamish. His legacy will be very long lived.
