Yellowstone National Park
This rutting, mature bull elk was bugling other bulls, bellowing, and ripping up the meadow of frosted grass as he protectively circled his harem of cows. Photographed at the height of the elk rut in autumn in Yellowstone National Park in the meadows along the Madison River.
Sharpened and light levels adjusted to add contrast.
