Jed and Miriam Einhorn and their son, Chaim, of Lakewood, N.J., set out from a trailhead from Mount Lafayette to hike a nine-mile loop. They called for 911 for assistance about 9 p.m. Tuesday. The couple are in their 50s; Chaim Einhorn is 31.
The family had a small light with them, but it was not sufficient for them to navigate the wooded trail.
New Hampshire Fish and Game conservation officers reached the Einhorns about 11:15 p.m. and escorted them down the mountain.
Lt. James Kneeland said the family was familiar with the trail, but did not allow enough time to complete their planned hike.
