Nathan grew up in Yellowstone National Park in the tiny community of Mammoth Hot Springs. His parents have been biologists and park rangers that have lived and worked in the park for 3 decades. Following in the family footsteps, Nathan studied biology at Montana State University where he earned B.S. and M.S. degrees. The ecology of mountain goats in the Absaroka Mountains on Yellowstone's eastern edge was his research topic. Further adventure in wildlife studies took him among moose in Alaska, guanacos in Patagonia, and pine marten in Idaho. His travels have led home as often as afar, where Yellowstone's coyotes, bears, river otters and gray wolves became primary subjects.
As a contributor to the historic gray wolf restoration project he has often been in the field tracking wolves. The Yellowstone Wolf Tracker, chronicles the adventures of wolf watching in the park. With the Yellowstone Association Institute, Nathan continues to teach about the mysteries of Yellowstone. His research at the University of Alberta focused on the relationship between wolves and elk after wolf reintroduction.
With his wife, Linda Thurston, Nathan has started his own wildlife tour group, The Wild Side, LLC, to continue leading groups to see wolves, orther wildlife, and all that Yellowstone and the wilds beyond have to offer. A defining purpose, if one can be offered for any person, would be to champion a land ethic that places the highest value on our wildlife and their habitats, and in so doing, forever preserve and enjoy the places that have provided his life's inspiration.
