I am back at Everest Base Camp and have been spending some time resting here after our ascent of Lobuche Peak. Tomorrow morning we will get up early and venture into the Khumbu Icefall for the first time. The Icefall is the challenging bit of terrain we need to navigate through to make our way into the Western Cwm. Our day tomorrow will be just spending a short bit of time in the icefall getting our feet wet and having some practice with the ladders that are used to span some of the sections.
Attached is a picture of the Khumbu icefall. Probably one of the single most challenging and dangerous parts of climbing Mount Everest from the South side.
Doug add: as Eric mentioned, negotiating the Khumba Icefall is an extremely dangerous part of the climb on the South route. For a deeper look into what it is like going through the Icefall from someone who has been there before, check out this post by Alan Arnette: Everest 2012: Into the Icefall.
