Bull elk, antlers bearing velvet, Gibbon Meadow. Elk are the most abundant large mammal found in Yellowstone National Park. More than 30,000 elk from 8 different herds summer in Yellowstone and approximately 15,000 to 22,000 winter in the park. Bulls grow antlers annually from the time they are nearly one year old. When mature, a bulls rack may have 6 to 8 points or tines on each side and weigh more than 30 pounds. The antlers are shed in March or April and begin regrowing in May, when the bony growth is nourished by blood vessels and covered by furry-looking velvet.

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.
