 another winter season at the 5,200' winter range near Gardiner, Montana. This is the only horned North American mammal that sheds it's "sheath" each year! Adult males grow a hard sheath made out of compacted hairs. The growth starts at the top of the dermal bone and works it's way down to the base. Pronghorn can run at 30 mph for 15 miles, with spurts up to 70 mph - making it the fastest land mammal in N. America! This image is currently available in multiple sizes.
