In the early-to-mid 1990s, a Bristol Bay native named David spent weeks alone at his grandfather's (Uppa's) cabin situated on the West Channel of the Nushagak River near Keeper Cutoff, due west of Portage Creek. While constructing a log generator shed, David was pelted by pine cones and endured three consecutive nights of heavy thumping on the cabin roof, later clearing off large clumps of uprooted grass and soil with a dip-net pole under the assumption that his brother was playing a prank. Setting a subsistence gill net in an adjacent narrow slough channel to harvest pike, David returned at dawn to discover his mesh meticulously woven through with thick alder branches. Days later, after a visit from his grandfather, David was foraging tundra moss blocks 100 yards out to finish the generator shed's roof when a severe silence enveloped the timber canopy. Returning to the site with a shotgun, he discovered his newly layered moss roof had been forcefully dragged down, tearing the tar paper backing.
That evening, he found his submerged gill net weighed down flush to the clear river bottom by an enormous stone, discovering clawless double bear-like print compressions on the bank. While reading by candlelight later that night, a powerful chorus of deep, ultra-long 'unnatural wolf howls' erupted from three points 300 yards out, forcing him to bolt across the door. The next day, while grilling pike on a spit, a massive guttural grunt blasted from the 30-foot structural tree clearance line. Upon pulling his net hours later, it was found entirely shredded with spruce boughs woven through. David returned to the cabin to find his freshly cut moss roof blocks had been cleanly torn away and stacked directly over the active fire pit to generate blinding white smoke.
The acoustic campaigns peaked with simulated wolf-howl and owl-hoot concerts in broad daylight. Two years later, while performing cosmetic repairs to a structurally compressed section of the cabin's rear roof line, David felt an immense dread and located identical double-impression tracks in a fresh dirt excavation. Reading that evening, an massive edge-of-vision silhouette dark movement blocked the main window pane. David circled the exterior with a Maglite and rifle, watching a giant shadow fade into the timber line. Upon firing a warning round, the cabin was subjected to a relentless 50-minute acoustic campaign of massive, rhythmic wood-banging patterns striking the logs every two seconds, causing the windows to rattle and forcing David into a fetal position until a final face-to-face window encounter at sunrise catalyzed his immediate boat flight.
