We're out of the office this week putting the finishing touches on the new studio! We'll be back with all-new shows the first week of August. Until then, enjoy a classic from the vault: "Grand Canyon Cold Cases." It's the episode that kicked off our Cold Cases series, and we've cleaned up the audio so it sounds better than ever. (Original air date: 2/17/23)

With over 52 million acres, the US National Park system is home to some of the most breathtaking natural features on the planet. Tens of millions enjoy the parks every year.  While most visits end with an amazing memory, many have not.  The official NPS cold case count stands at 29, however, independent researchers estimate between 1100 to 1600 unsolved disappearances originate in our parks.  Join us this week as we begin the mini-series, “National Park Cold Cases”.  Cases covered in this episode; Justin Richardson, Drake Kramer, and Morgan Heimer.

Locations Unknown ventures into the silent, vast spaces where people have simply gone missing. Hosts Mike & Joe guide each episode through a specific case, piecing together timelines from the final known moments, through the often-frustrating official searches, and into the lingering questions that haunt families and park rangers alike. This isn't just a true crime podcast; it’s a close look at the intersection of human error, unpredictable nature, and the peculiar geography of places like dense national forests and isolated mountain ranges that can swallow a person whole. You’ll hear about the decisions made in the critical hours, the terrain that complicated everything, and the community of experts and amateurs who keep looking. The show naturally explores how these landscapes, while beautiful, hold secrets, making the wilderness itself a central character in every story. Tune in for a respectful, detailed examination of stories that end not with a conclusion, but with an open map and a deepened mystery. The podcast digs into the cultural fascination with these vanishings and what they reveal about our relationship with the wild, remote corners of the country.
