Elk at Tule Elk National Wildlife Refuge. Once estimated to have a population of fewer than 30, these unique Tule elk now number more than 4,000. See them — and other terrific wildlife — just two hours outside of San Francisco, California. Photo by Lee Eastman, U.S. Fish and Wildlife Service. From the US Department of the Interior blog.

Two elk smooch while enjoying the view at Rocky Mountain National Park in Colorado. Every autumn, elk gather for the rut or annual mating season. Bull elk can be heard calling to females with a crescendo of deep, resonant tones that rise rapidly to a high-pitched squeal before dropping to a series of grunts.
