The summer throngs descend upon Boiling River in Yellowstone. The geothermal soaking site swells with visitors in summer. And, it just happens to reside within a wildlife migration corridor used by elk, bison, mule deer and bighorn sheep. Everybody wants to have fun and soaking at Boiling River is an exotic experience. Having fun is good for our physical and mental health. But the mere act of being an outdoor recreationist does not make one a conservationist. Photo courtesy Jim Peaco/NPS
