"Bread for a hungry bruin?" Blond bear begs in Yellowstone, but children obey park rules: Don't open windows or offer food. Cyclops eye of Yellowstone's Morning Glory Pool ogles a ring of admirers. A violent earth quake in 1959 lowered the water's average temperature by 10° to a still-hot 158° F.; as a result algae now thrive, staining the rim of the pool. Fisheye lens captures the shadow of the photographer with his camera on a rod.
