Morning Glory Pool has long been considered a must-see site in Yellowstone. At one time a road brought visitors to its brink. Over the years they threw coins, bottles and trash in the pool, reducing its flow and causing the red and orange bacteria to creep in from its edge, replacing the blue bacteria that thrive in the hotter water at the center of the pool. The pool is now accessed only by a foot path. Upper Geyser Basin.

Large male elk (bull) in snow covered meadow near Madison River. Only male elk have antlers, which start growing in the spring and are shed each winter. The largest antlers may be 4 feet long and weigh up to 40 pounds. Antlers are made of bone which can grow up to one inch per day. While growing, the antlers are covered with and protected by a soft layer of highly vascularised skin known as velvet. The velvet is shed in the summer when the antlers have fully developed. Bull elk may have six or more tines on each antler, however the number of tines has little to do with the age or maturity of a particular animal.

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.
