Episode 29 deals with a ghostly location right here in New England: The Hoosac Tunnel in western Massachusetts, also known as The Bloody Pit. During its 25 years of construction the tunnel claimed almost 200 lives. Do some of those spirits still wander within the dark walls?

This episode deals with the weird little urban legend of black-eyed children. Have they actually been spotted by folks, or was it just innocent kids being misunderstood? Why are they such harbingers of doom? Where do they come from?

This is our third and final episode about SKINWALKER RANCH -- the property in rural Utah that is absolutely teeming with paranormal weirdness -- and in this installment we share all of our theories on the place. Is it just a bunch of natural phenomena getting everyone worked into hysteria? Is it an elaborate hoax? Is it a thin place, where the border between this dimension and the next is more transparent than we might be used to? Listen in to find out what we think!

Welcome to Part 2 of our SKINWALKER RANCH series! While the first episode dealt with the family's 18-month experience living at the ranch, this one delves into the scientific investigation that took place shortly after. The National Institute for Discovery Science -- aka NIDS -- team saw some WILD stuff, and we talk all about it!

In this episode of Unknowable we delve into the first of three parts on SKINWALKER RANCH. This is a plot of land in Utah that has been known to host just about every weird thing you can imagine: UFOs, portals to other dimensions, mysterious orbs, Bigfoot-like creatures, poltergeists, and, of course, the skinwalkers themselves...

This week's episode stays on the medical theme with Gloria Ramirez, who was dubbed "The Toxic Woman" after her mere presence in an emergency room caused 23 people to become ill, 5 of which were hospitalized. Was it truly a purely coincidental string of chemical reactions, or is there something more... unknowable at hand?

This week's episode goes down a more medical path than we're used to... we're talking about prion diseases! Yes, degenerative brain diseases that occur 85% of the time completely sporadically, with no explanation for why or even exactly how. Justine tells us about kuru, the prion disease that spread among the Fore people of Papua New Guinea thanks to their propensity to eat human brains. Gray tells us about fatal insomnia, the prion disease that literally kills you by not letting you sleep. Prepare to be scared, friends.

Oh yes, we did it: A BIGFOOT EPISODE. Probably one of the most well-known mysterious animals to exist. Is Bigfoot an elusive breed of mammal, or something a bit more paranormal? All we know is that they're fascinating!
