Doug Peacock, the Green Beret medic who served in Vietnam, has become a leading voice in grizzly bear conservation and recently co-founded Save the Yellowstone Grizzly (https://savetheyellowstonegrizzly.org). In his earlier years, Peacock took part in the Greater Grizzly Search trying to determine if bears are inhabiting both the Selway-Bitterroot Ecosystem and the southern Rockies in Colorado.
