Ralph Mahan founded Yellowstone Hiking Guides in 2014 with Josh and Emily Jo. His passion for the outdoors was contagious. One of his most fond memories was hiking with Josh in 1979 in Grand Teton National Park when more than 200 elk stampeded in front of them on the trail. He described the moment as an unforgettable thundering, shaking the ground beneath his feet. Ralph loved everything about Jackson; hunting, fishing, friends, etc. He spent his retirement in Camarillo, California hanging out with family and friends next to the Channel Islands National Park.
