The Rocky Mountain Elk (Cervus canadensis nelsoni) is a Western North America subspecies of elk found in the Rocky Mountains and adjacent ranges. In the winter, elk are mostly found in lower elevation open forests and floodplain marshes. In the summer the elk migrates to the alpine meadows and subalpine forests. Elk can reside in a diverse range of habitats but are most often found in forests and forest edges. In mountainous regions they often stay at lower elevations in the winter and migrate to higher elevations during the warmer months. This herd of elk was photographed while grazing in a meadow on Campbell Mesa near Flagstaff, Arizona, USA.
