Baxter State Park officials warn of risks after rescuing pair on Sunday
A man and his son had to be rescued after becoming disoriented on Baxter State Park's Knife Edge Trail Sunday.
Park officials say whiteout conditions from blowing snow caused problems.
Rangers saw their headlamps on the Dudley Trail which has been closed for quite some time because of rockslides.
The two men had lost the trail and had fallen several times because of conditions and unsuitable gear.
Their injuries, including frostbite, are minor.
A ranger and a volunteer led the pair to the Chimney Pond Ranger Station around midnight.
Rangers say the chances of losing the trail or becoming injured are magnified in winter when rescue may be hours away.
