Old Man's Loss Felt in New Hampshire
FRANCONIA, N.H. — Crowds of visitors were drawn to Franconia Notch on Sunday to mournthe loss of New Hampshire's well-known symbol — the Old Man of the Mountain granite profile. The 700-ton natural formation was just a pile of rocks after breaking loose from its1,200-foot-high mountainside perch. It was unclear when the outcropping fell because clouds hadobscured the area Thursday and Friday; a state park trail crew discovered the collapse Saturdaymorning. The famous mountain's history dates millions of years. Over time, nature carved out a40-foot-tall profile resembling an old man's face, and it eventually became New Hampshire's mostrecognizable symbol.
