Spring Buck, Yellowstone Nat'l Park, WY
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!
