The Four Day Summit Climbs led by RMI Guides Andres Marin and Geoff Schellens were forced to turn at the traverse to the nose of the cleaver (11,000’) due to unstable snow. The teams performed snow tests which confirmed the snow instability. The weather this morning was clear but windy with gusts of 45 mph as the teams descended back to Camp Muir. The Expedition Skills Seminar – Muir led by RMI Guides JJ Justman and Pete Van Deventer are making their ascent to Camp Muir today to begin their week of training and climbing.
