Keith Sidle

Originally from the Northeast, Keith began climbing trap rock cliffs in Connecticut and ice in Mount Washington Valley before heading west and eventually joining AMS in 2013. With over a decade of guiding experience, and with a particular affinity for sharing his love of ice climbing, Keith is a natural instructor on our mountaineering courses. He also guides Denali expeditions for the school. Keith currently splits his time between Alaska, Wyoming, and New Hampshire. When not guiding, he can often be found looking up at a frozen waterfall, contemplating its ascent.
