Surprise grizzly bear encounter in Wyoming's Grand Teton sends Massachusetts man to hospital

Just as the busy summer tourist season is kicking off in Grand Teton National Park, a surprise encounter with two grizzly bears seriously injured an unnamed 35-year-old Massachusetts man, who was airlifted by helicopter to an ambulance which subsequently drove him to the hospital.

The park service stated that the victim is "in stable condition and is expected to fully recover." 

The attack occurred on the Signal Mountain Summit Road, leading to the Signal Mountain Trail, a popular 7,723' peak on the eastern bank of Jackson Lake.
