Winter Ecology


  • Track wildlife via snowshoe

  • Observe and study wolves with a park expert

  • Visit incredible geothermal features


Winter in Yellowstone is a dynamic and thrilling season. Bison crowd around thermal pools while the park's predators prepare their own winter strategies. Travel and learn with EPI - you'll go beyond what most park visitors see by working with park researchers, studying animal tracks by snowshoe, and heading to the Lamar Valley for a day of wolf observation.

Your Fieldwork

Track wildlife with telemetry

During the winter, wildlife gathers in Yellowstone's valleys. Use telemetry to track elk, bison, and other species. Measure snow depth and habitat use, and collect fecal samples used to analyze diet as part of Yellowstone's Home on the Range study.

Partner Profile

Chris Geremia is a senior bison biologist for Yellowstone National Park.  He began his career in Yellowstone nearly twenty years ago as a field technician, a period of "wandering around the park" that he describes as some of the "greatest years" of his life. Geremia now holds a PhD in Ecology and is the principal investigator on Yellowstone's Home on the Range study. The arc of his career, his deeply felt connection with the landscape and its inhabitants, and his eagerness to talk with students has made him an incredible partner for EPI and an inspiration to many.
