JAFFREY, N.H. (CBS) – A Winchendon woman was injured Sunday while hiking in New Hampshire when she tumbled over a rock ledge after night fell and she was lost without a light. Fortuantely, rescuers were able to locate the woman even though her cell phone battery died during a 911 call.

The woman called 911 around 8:25 p.m. to say she was on the White Arrow Trail at Monadnock State Park without a light and it had gotten dark. Less than a minute into the call with conservation officers, the woman’s phone died.

Dispatchers were able to provide GPS coordinates for the woman’s location. The 40-year-old woman was about half a mile up the mountain from the end of Old Toll Road in Jaffrey.

When the woman’s cell phone died, she began to panic and started hiking down the trail in the dark. She made it about 500 feet when she fell off a rock ledge that was about 20 feet high and landed on the rocks below.

New Hampshire Fish and Game said the woman began her hike around 6 p.m. and was not properly dressed for conditions. They said the situation could have “had a much different outcome” if the woman wasn’t able to make one last call to 911 before her phone died. The area is also known to have poor cell phone coverage.
