Mount Hayes, rising to 13,832 feet, is the tallest peak in the eastern Alaska Range and sits within the infamous Alaska Triangle, a region linked to over 2,000 disappearances since the 1970s. Paranormal interest surged after a declassified CIA document from Project STARGATE described a possible underground alien base beneath the mountain, with remote viewers allegedly perceiving non-human entities operating advanced technology. Sightings of glowing orbs, fast-moving lights and radar anomalies have been reported since the 1950s, including recent footage of a green light hovering and vanishing behind the peak. Sightings continue to be reported in local news, Reddit threads, and paranormal forums. Theories about missing satellite data and recent disappearances (e.g. Brian Erickson in 2023) have kept the area in public focus.
