Mixed climbing technique

While alpinists have used mixed climbing techniques for decades on alpine routes (most north-facing alpine routes are iced or snow-covered), mixed climbing as a standalone sport came to wider prominence with Jeff Lowe's ascent of the partially bolted Octopussy (WI6, M8 R) in 1994. Mixed climbing also led to the sport of dry-tooling, which is mixed climbing on routes that are completely free of all ice or snow. The equipment used — the lengths of ice tools and the use of heel spurs and ice axe leashes — has become more regulated to avoid concerns of being more like aid climbing than free climbing.
