Mark Newcomb grew up in Wilson. He earned a BA in geology from Carleton College in 1990. He worked as a mountain guide for 18 years, leading climbs and treks in the Tetons, Nepal, Tibet and Alaska. In 2010 he earned an MS in economics and finance from the University of Wyoming. His thesis topic was to design a carbon dioxide pipeline for Wyoming and calculate a tariff for shipping carbon dioxide through it. Back in Jackson, in lieu of designing pipelines, he has worked on projects including a study of the economic contribution of winter backcountry recreation, impacts of climate change on Teton County’s economy, and energy projects centered around improved coal utilization techniques.
