Alaska Triangle (Portage Pass corridor)

OVERVIEW

The area around Portage Pass and Prince William Sound sits inside what is commonly called the "Alaska Triangle," a vast, sparsely populated region roughly bounded by Anchorage, Juneau, and Utqiagvik where search-and-rescue records show an unusually high number of unresolved disappearances.

REPORTED ACTIVITY

On October 16, 1972, a plane carrying U.S. Representatives Hale Boggs and Nick Begich vanished on a flight from Anchorage along this route toward Juneau; the ensuing 39-day search, the largest in Alaska history at the time, found no trace of the aircraft or its occupants. The case remains unsolved and is frequently cited, including in History Channel programming, as emblematic of the wider Alaska Triangle pattern.

VISITING
