About David Jaffee

Geology & Glaciology Presenter and Guide


For over 20 years, David has guided and taught a variety of audiences about our natural world and our connection with it. His childhood interest in natural systems eventually brought him to Evergreen State College, where he earned a B.Sc. in Environmental Studies and Geology, followed by an M.Sc. in Applied Ecology from the University of Vermont. Mingling an academic background with experience working around the world in exceptionally diverse environments, he is able to efficiently observe, understand and interpret natural and cultural history.

David has climbed onto an elephant in Nepal, looked into the eyes of masked boobies in Galapagos, sought nudibranchs on the Great Barrier Reef and walked the Ghats along the Ganges River in India. He has led backcountry trips in Denali National Park and Preserve, learned from students in Kentucky and gained great insights while hitchhiking home from work in Yosemite National Park. In addition to working for 6 seasons in Denali National Park and Preserve, David has been part of many expeditions in southeast Alaska on various ships. He has experience as a naturalist in many of the lower 48 states and Baja California and has worked as a divemaster in Australia, Costa Rica and India.

David also assisted with the establishment of a marine protected area off the coast of Madagascar and researched birds in Canada and South America. His enthusiasm about the natural world is contagious.
