For the second time within five days, lost hikers were rescued from Pisgah State Park.

Conservation officers with the N.H. Fish and Game Department retrieved a Keene woman and her daughter Friday night when they couldn’t find their way back to the trailhead.

Amy Bartlett, 45, and her 17-year-old daughter left the Kilburn Loop trailhead on Route 63 in Chesterfield at 5 p.m. for what they thought would be a quick hike to take pictures of Pisgah Reservoir, Lt. William Boudreau of the Keene office of N.H. Fish and Game said, but darkness fell and they found themselves walking in circles for several hours. With only the light from their cell phones, he said, they were unable to locate the path back to the trailhead, where they had parked.

With one cell phone dead, Boudreau said, Bartlett used the other at 30 percent power to call 911. “That spot has weak cell service,” he said. “She was lucky to get a call out to 911. All I heard her say was ‘Pisgah Ridge Trail,’ and I had her coordinates.”

A conservation officer rode his all-terrain vehicle from the Reservoir Road parking area in Winchester approximately two miles to the lost hikers, according to the Fish and Game report of the incident. The mother and daughter were located at about 10:40 p.m. on the north end of the reservoir.

The officer brought the pair out of the woods and transported them by cruiser to their vehicle at the Kilburn Loop parking lot, according to Fish and Game. No injuries were reported.

On Aug. 10, another hiker was rescued when he became lost in a large expanse of challenging terrain within the 13,300-acre park.

New England K-9 Search and Rescue had to be called in to aid local law enforcement officers in locating Noah Pepera-Rudd, 29, of West Chesterfield, who was found dehydrated but uninjured a little after 3 a.m. in a large swamp “quite a ways” from Horseshoe Road in Chesterfield, where he began his hike at 7 p.m., Boudreau said.
