A tour boat carrying about 50 people overturned Sunday on a lake in upstate New York, police said.
The 40-foot (12-meter), glass-enclosed boat capsized shortly before 4 p.m. (2000 GMT) on Lake George about 50 miles (80 kilometers) north of Albany in the Adirondack Mountains.
The Warren County Sheriff's office confirmed the boat had flipped but could not say if anyone was injured or if there were still people in the water.
The weather was clear, calm and in the 70s (21 degrees Celsius) Sunday afternoon.
Representatives of Shoreline Cruises, which operates the boat, could not immediately be reached for comment, AP reports.
