FISHING BRIDGE, Yellowstone National Park. Both sides of Fishing Bridge are crowded during the short summer season. People from the East and the West, the North and the South, rub elbows here, discussing the affairs of the Nation. Although a curtain of fishing lines drops into the water below, discussions of the old "cracker barrel" type seem of more importance than the catch. But park rangers report big excitement when the line of the occasional fisherman on the upstream side floats down, tangles with a line on the down-side—and each fisherman, after much tugging, thinks he has a big catch. The disappointment also is great when the truth comes out.

TENTING TONIGHT, Mount Rainier National Park. Hardy climbers bivouac on the eastern side of Mount Rainier. The glacier-carved cliffs of Little Tahoma Peak, at the right, show how lava flows alternated with deposits of ash, cinders, and pumice. Guided parties make the climb from Paradise Valley, on the southern slopes of Mount Rainier, stopping overnight at 10,000-foot high Camp Muir. (Photograph by Bob and Ira Spring.)
