Once the foreman of Beacon Hill's abandoned limestone quarry, he never left when operations shut down decades ago. The isolation and constant exposure to blasting powder drove him completely insane, and he now treats the old quarry sites scattered throughout the disc golf course as his personal killing fields. When the horror film crew arrived, they thought he was just another local actor until the first 'accident' involving real dynamite.

The Quarry Maniac appears as a hulking figure in a tattered hard hat and reflective safety vest, his face obscured by decades of limestone dust and madness. He carries vintage mining tools converted into weapons and has an uncanny ability to predict where players will throw based on his knowledge of the terrain. His presence is often announced by the distant sound of machinery starting up or small controlled explosions echoing through the mountain.

He stalks players who venture into the more remote areas of Beacon Hill, particularly around holes that incorporate natural rock formations or elevation changes. The Quarry Maniac uses his industrial knowledge to create elaborate traps involving falling rocks, unstable ground, and strategically placed obstacles that force players into increasingly dangerous positions.
