AMERICAN PRONGHORN

Pawnee National Grasslands, Colorado, USA

by Robert M. Palmer

Milliken, Colorado, USA

“I took this image from a vehicle as a herd of about 25 American pronghorn were crossing a ravine beside the road. The photographic challenges were anticipating where they would cross and how to get the very best light on them. I cropped the image to emphasize the horizontal composition.”

The Pawnee National Grasslands cover 193,000 acres and is home to the fastest mammal in the western hemisphere, the pronghorn, which can sprint at speeds up to 60 miles per hour. Once numbering in the millions, pronghorn were reduced to about 20,000 by the 1920s. Their numbers are now rebounding as lands are preserved for wildlife habitat.
