Don and Tina were hired to operate a remote, one-man mining claim in the Koyukuk River drainage. After the owner departed due to flight delays, the pair spent three days working pay-dirt during a period of torrential rain. The isolation was punctured by heavy, percussive bangs—as if large rocks were hitting the metal mining equipment—that occurred regularly.
One rock ricocheted near Don, leading him to spot a dark figure retreating into the shadows. The harassment escalated at their cabin site, with rocks hitting their structure during the night. Despite being armed with a .45-70 rifle and a 12-gauge, the couple felt overwhelmed by an oppressive sense of unease.
They eventually abandoned the claim after witnessing the entity at close range, describing it as an immense, dark-haired humanoid that moved with startling agility. They successfully retrieved their earnings but left the equipment, noting the area's history of mysterious disappearances, including a hunter who vanished without a trace nearby.
