Possible vocalizations heard by hunter at Bear Lake summit

The witness was hunting alone from a ridge when repeated very loud, short guttural shouts or growls approached from about 200 yards to about 75 yards, accompanied by rapidly approaching breaking brush. He never saw the source but readied a camera and rifle while waiting motionless. After a spooked cow moose ran through a distant saddle, he threw rocks and fired a shot with no response and then left.
