Expert Instructors, Real-World Lessons

CMC Faculty Partner with the Colorado Avalanche Information Center

Highly regarded industry experts developed the Avalanche Science program. Their invaluable experience in the nation’s most active snow sports region shaped the curriculum. This expertise is available to you through CMC’s partnerships with the Colorado Avalanche Information Center, nearby ski areas, and leading industry professionals who will teach you both in the classroom and on the mountain slopes.

During your field internship, you’ll have the opportunity to monitor, track and measure mountain snowpack over two full winters and observe how snow behaves in various weather conditions.

Hands-on learning activities include:

  • Performing high-altitude fieldwork in the Rocky Mountains
  • Observing snow behavior at CMC’s on-campus snow study plot
  • Tracking data from two remote-sensing weather stations: one on campus and one in the nearby Sawatch Range
  • Using state-of-the-art equipment in daily lessons
  • Meeting in “smart” classrooms that deliver the latest technology
  • Learning in hybrid classes that combine online and on-site education to fit the schedules of working students
  • Access to a regional forecasting office and personnel

  • M.A. Physical Geography Hydrology, University of California, Santa Barbara
  • Ph.D. Physical Geography Hydrology Statistics, University of California, Santa Barbara

Professional Certifications and Associations

  • American Avalanche Association, Certified Instructor
  • American Geophysical Union


Dr. Kelly Elder is a research hydrologist with the USDA Forest Service at the Rocky Mountain Research Station in Fort Collins, CO. He studies water distribution and the water yield from mountain snowpacks and his specialty is snow. He has worked to develop information and methods for measuring snowpack properties, distribution of snow cover and water equivalents in alpine and subalpine basins. Dr. Elder’s passion for snow hydrology and mountain climatology can be found in his numerous scholarly articles and professional publications.

In addition to his research efforts, Dr. Elder served as a faculty member for the Colorado State University Watershed Science Program from 1995 - 2000. He has taught courses on snow, avalanches, snow hydrology, physical geography and the geography of water resources.

As an expert in the snow science field, Dr. Elder was involved in the development of the Avalanche Science program from concept to curriculum. He hopes that students graduate the program with a fundamental working knowledge that will allow them to pursue careers in the industry and benefit from the hands-on, applied approach.

“The Colorado Mountain College Avalanche Science program is designed to prepare snow and avalanche professionals for career paths in a new comprehensive fashion not available in any other venue.” says Dr. Kelly Elder, “It will change the way we train and prepare people for the professional snow worker industry.”

When he isn’t “buried” in avalanche and hydrology research or teaching students, Dr. Elder enjoys skiing at Arapahoe Basin, and spending time with his children and dogs.

Dr. Ethan Greene is an Avalanche Science instructor at Colorado Mountain College LeadvilleAbout

Dr. Ethan Greene has been the Director of the Colorado Avalanche Information Center (CAIC) since 2005. He currently lives in Leadville and grew up in Boulder, skiing Colorado’s Front Range. Prior to his time with the CAIC, Ethan spent several winters in the San Juan Mountains, at Big Sky Ski Resort as a ski patroller and at the Forest Service Utah Avalanche Center as an avalanche forecaster. Ethan approaches snow and avalanches from both a practical and theoretical perspective.

Ethan has studied meteorology at the University of Utah and Atmospheric Science, specifically snowdrift formation, at Colorado State University. He has also examined and researched the microstructure of snow and its metamorphism in Colorado and Switzerland, earning a Ph.D. in Geosciences. Ethan has published various scholarly articles on snow, weather and avalanches and been a member of national and international working groups on snow and avalanche projects.

Dr. Ethan Greene is one of the original supporters of the Avalanche Science program and helped with the initial efforts to design and approve the curriculum. As an avalanche professional, Dr. Greene recognized the need for an experiential based program geared towards industry professionals.

He specifically looks forward to showing students how to define and address avalanche safety problems and preventing avalanche tragedies in Colorado.

“The Avalanche Science program gives students a chance to dig into the fundamentals of snow, avalanches and provides time to learn, experience and experiment.” says Dr. Ethan Greene, “I look forward to meeting, teaching, and working with a fantastic group of people.”
