The man, who was visiting from Massachusetts, was "seriously injured by a bear in the area of the Signal Mountain Summit Road," officials stated.

Per the website, it's thought one of the two grizzly bears injured the man, who authorities have not named.

"Based on initial reports from the injured visitor and preliminary information conducted as part of an ongoing investigation of the site, law enforcement rangers and park biologists believe the incident was a surprise encounter with two grizzly bears, with one of the bears contacting and injuring the visitor," the release added.

The website confirmed that Signal Mountain Summit Road and the Signal Mountain Trail were currently closed to the public.

Per the NPS website, visitors are reminded that they should never leave food unattended unless properly secured, as well as to keep their camp clean and store everything in a bear-resistant food locker/bear box or keep it in a hard-sided vehicle with the windows rolled up.

If you choose to watch or photograph the bear, use a spotting scope, binoculars, or telephoto lens," the authorities stated. "Park in designated areas, and never block travel lanes. Follow the directions of staff in places where bears are sighted,"
