ACADIA NATIONAL PARK – Rangers responded to four calls for help within a one-hour period Tuesday and got all the injured visitors to hospitals with the help of the Bar Harbor ambulance service.

Ranger Richard Rechholtz said the first call at about 1 p.m. involved helping an 80-year-old man who fell on the granite steps at Thunder Hole, a popular site near Sand Beach.

Moments later, a woman was banged up when she fell from her bike on the Loop Road below Sand Beach. The third call involved a woman who fell while walking on a trail near Jordan Pond, injuring her hip. The final call was the most serious, Rechholtz said, when a man suffered a mild heart attack on Sand Beach.

The rangers were still compiling reports on the incidents late in the day Tuesday; therefore, names, ages and other details were not available.

Rechholtz said none of the injuries was life-threatening.

He said the Bar Harbor ambulance transported the elderly man and the heart attack victim, while rangers transported the other two victims in park vehicles. The second ambulance had responded to the Jordan Pond call and was diverted to Sand Beach when the heart attack call was received moments later.
