The Lower Falls of the Yellowstone River drops 308 feet at the head of the Grand Canyon of the Yellowstone. A long exposure blurs the fast-flowing water. The canyon is approximately 10,000 years old, 20 miles long, 1000 ft deep, and 2500 ft wide. Its yellow, orange and red-colored walls are due to oxidation of the various iron compounds in the soil, and to a lesser degree, sulfur content.

Male elk (bull) alongside female elk in grassy meadow, during rutting season. A bull will defend his harem of 20 cows or more from competing bulls and predators. Only mature bulls have large harems and breeding success peaks at about eight years of age. Bulls between two to four years and over 11 years of age rarely have harems, and spend most of the rut on the periphery of larger harems. Young and old bulls that do acquire a harem hold it later in the breeding season than do bulls in their prime. A bull with a harem rarely feeds and he may lose up to 20 percent of his body weight while he is guarding the harem.
