Soon, elk rutting season will begin. Herds of elk are making their way into the Estes Park valley (Colorado, USA) from higher elevations to gather for the annual mating rites. It’s a great time for people to come and listen to the males bugling and watch them duel. But from afar, folks! A male elk in rutting season is not something you want to come face to antler with. I captured this picture from the highway (U.S. 36) near a home in Estes Park in early December 2007.
