Back in the late 1990s, Joseph was staying alone overnight to guard supplies at an unfinished family cabin along the remote Nushagak River. The cabin was still under construction, lacking finished window panes and leaving open, rough-framed cutouts directly into the wilderness. As dusk fell, Joseph heard an unsettling, unusually loud howl echoing miles away that sounded like a poor imitation of a wolf. Within an hour, the unnatural howling had closed the distance, sounding less than 200 yards away from the cut bank before falling dead, unnervingly silent.
