I live in AK. Mr Gremlin heard it that morning (not sure why I didn’t wake up because normally I’m a light sleeper) and thought it was someone doing live round drills at the nearby army base or some large critter scratching/banging at our house. Nope. Took a few days for us to realize what he’d heard. Wild stuff.
There’s a pretty robust Tongan population in Alaska and the local NPR station has been playing some really heartbreaking interviews.
