Yellowstone park rangers will impress you with their knowledge, dedication and enthusiasm. This museum's exhibits and short films explain how the ranger's role evolved at Yellowstone from a quasi-military function to specialists who educate the public, maintain the ecological balance of the park and work hand-in-hand with researchers. Late May-September daily 9 am-5 pm. Norris Campground, off the Grand Loop, Yellowstone National Park.
