A South Portland woman who injured her back while hiking on Mount Major in Alton, New Hampshire, had to be carried more than a mile by rescuers to the trailhead parking lot on Sunday.

Brittany Kelley, 31, was with three hiking companions when she suffered a back injury shortly after reaching the summit around 4 p.m., according to a news release issued Monday by New Hampshire Fish and Game.

“Kelley was unable to walk due to her debilitating back injury and she was approximately 1.5 miles from the trailhead parking area,” New Hampshire Fish and Game said. The group of hikers contacted 911 for assistance.

Alton, New Hampshire, Fire and Rescue, Gilford Fire and Rescue, Lakes Region Search and Rescue, and New Hampshire Fish and Game responded. Kelley was stabilized and transported by rescue litter to the trailhead.

She was transported by ambulance to Frisbie Memorial Hospital in Rochester to be evaluated and treated.

Mount Major is 1,148 feet tall and regarded as a moderately challenging hike that takes an average of two hours and 14 minutes to complete. It is a popular area for hiking and snowshoeing.
