Possible evening vocalizations heard near Snowbowl

August 2007 late afternoon- early evening Flagstaff, Coconino County, Arizona 2 witnesses

Account

The witness and a relative were doing sunset photography from a parking lot above forested hills. They heard an extremely loud single scream or roar coming from the forest several hundred yards below, on two occasions that evening, which others in the lot also noticed. The sound was described as starting low and building, with power and a chorus-like quality that seemed beyond a single human, and did not match any known animal to them.
