Authorities were searching Thursday for a Maryland man reported missing at Grand Canyon National Park.
Park officials said they received a report around 9 p.m. Tuesday about an overdue backpacker in the vicinity of the Walhalla Plateau on the canyon’s North Rim.
They said 66-year-old Clifton “Cliff” Beck of Mount Airy had obtained a backcountry permit to spend two nights on the Walhalla Plateau.
It is believed that Beck is traveling alone. He was expected to exit the backcountry last Sunday.
