VICTIM OF A SERIOUS ACCIDENT, Yellowstone National Park. Sometimes motorists become careless in the national parks when a good road leads straight ahead. They even fall asleep sometimes and go off the road and over an embankment. Here rangers transport up the Gardiner River Bank the body of a man from a wrecked car in the river.

PARK RANGERS ON WAY TO TAKE SNOW DEPTH MEASUREMENTS. Information as to the depth of the snow in the mountains is a gauge by which neighboring town and ranch people can estimate their water supply, come spring and summer. The rangers also make ski and snowshoe patrols in the course of protecting the park wildlife. (Photograph by Condon.)

FISH PLANTING. Rangers restock park lakes and streams so that visitors may enjoy fishing. State Fish and Game Commissions and the U. S. Fish and Wildlife Service cooperate. Fingerlings are carried in cans to the park waters—on trucks to waters near the roads and on horseback to the backcountry. Here a ranger is tempering the water in the cans before releasing the young fish.
