Wild bison roam a portion of Grand Teton National Park where once there were private cattle ranches. The animals, descended from bison in Yellowstone that survived near extinction, wandered into the park decades ago and found a home. Owed to conservation ancestors of a century ago and carrying forward to today with elders like Chouinard, Goodall, their contemporaries and younger generations, parts of the American West are only protected because citizens rose in defense of wild nature when it mattered most.
