Entirely unique on this planet, the Pronghorn's scientific name, Antilocapra americana, means "American antelope goat." But the deer-like Pronghorn is neither antelope nor goat -- it is the sole surviving member of an ancient family dating back 20 million years.

Leaping Antelope Knocks Couple Off Speeding Motorcycle

Monday, June 22, 2009

GRAND TETON NATIONAL PARK, Wyo. — An antelope running across a road knocked a couple off a motorcycle as they drove through Grand Teton National Park.

Park officials say 38-year-old Brady Burgess, of Garland, Utah, was driving the bike and had just passed a motor home at 65 mph when the antelope leaped and struck the motorcycle sideways Saturday. The animal knocked the couple off the bike, which fell over and slid 100 feet down U.S. 26/89/191.

Forty-six-year-old Koreen Burgess was transferred Sunday from St. John's Medical Center in Jackson to University of Utah Health Sciences Center in Salt Lake City. Her condition wasn't immediately available.

Burgess was in good condition at St. John's.

The accident closed the highway for an hour.
