October 2006 Morgan, Morgan County, Utah Class B #16744

Possible vocalizations heard near East Canyon Reservoir

The witness reports hearing very loud recurring screams and hoot-like sounds coming from canyons near a relative's home in northern Utah over several years, first paying attention to them while camping overnight with a young relative. The sounds are described as fierce, deep, growling and primate-like with a low-frequency component, with calls lasting up to about 15 seconds in series of five or six, sometimes followed by whoops, heard at dusk or night from a mile or so away. Other family members are reported to have heard the same vocalizations over about ten years. The witness, described as a hunter familiar with native animal sounds, found alleged bigfoot recordings similar but not exactly the same.
