CAMPFIRE PROGRAM AT PUBLIC CAMP GROUND, Mount Rainier National Park. After a day of hiking, climbing, horseback riding, or other strenuous activity, campers at the Ohanapecosh Campground relax and learn—at a campfire program conducted by a park naturalist. This shows the average attendance, but often the crowds are much larger, with at least half the audience standing.

JUNIOR NATURE SCHOOL, Rocky Mountain National Park. For many years park naturalists have conducted weekly nature schools for children in Rocky Mountain. This program has attracted the enthusiastic attention of both children and adults.

A WELCOME GROUP, Yosemite National Park. No organized group of campers ever received more attention in Yosemite than did these children from a hospital for crippled children in nearby Merced County. Special arrangements were made to give them the most convenient campsite possible.

MUSIC 'ROUND THE CAMPFIRE, Yellowstone National Park. The campfire, a symbol of the Old West, is especially appropriate to the national parks. To the pioneers the campfire meant comforting heat, safety from wild animals, fellowship on the long treks through the wilderness. In the national parks today visitors gather around informal campfires where good fellowship prevails as East meets West under the trees and the stars. (Photograph by Andrew T. Kelley.)
