Under the umbrella of SPCC, the ICEFALL DOCTORS construct the route on Khumbu Icefall. Khumbu ICEFALL is an extremely dangerous and fragile terrain between Everest Base Camp (5365m) and Camp 1 (5900m) filled with deep crevasses and leaning blocks of ice. The route collapses frequently and a new route has to be built in those sections. SPCC annually fixes the ropes and ladders on KHUMBU ICEFALL.
