Howl Isabella County Main reports Clear all
2011–2012 Isabella County, Michigan Class B #32981

Farmers record interesting vocalizations west of Clare

The witness reports repeatedly hearing unfamiliar sounds at a central Michigan farm over the prior summer, often while doing outdoor animal chores at night with two other people. The sounds included howls, wood knocking, deep guttural noises, whoops, and indistinct talking-like vocals, which the witness recorded and felt matched published bigfoot recordings.

Growl near Isabella County

The witness visited a central Michigan farm property late at night to retrieve recorders. A powerful growl was felt in the chest from a distance, followed by two vocalizers calling back and forth while moving away. The exchange lasted many minutes and was partially recorded after the witness restarted equipment.

A quick ask from the person behind the Anomadex: if you allow analytics, Google Analytics shows me which places, phenomena and searches you're most curious about. That tells me which regions and sources to add next and what to make easier to find. It never sees your name or anything you send me, and nothing is set unless you say yes. Privacy
