When not personal climbing across the US Mark divides his time guiding extensive Alpine, Ice, Rock and Ski trips in the North Cascades, Coloradoâs San Juans, and European Alps. Markâs shoulder seasons are typically spent by annual spring migrations to Alaska to alpine and ski guide in the Alaska and Chugach ranges, rock guide in Red Rock NV and Joshua Tree CA, or high altitude mountaineering in Nepal.
Markâs personal interests are alpinism and ski mountaineering descents in areas that still need exploring. His academic background is in geology with an emphasis on mountain building processes. On his days off he explores the undiscovered corners of his back yard â the North Cascades and San Juan Mountains.
