A few years prior to 2023, Heather and Carl flew via floatplane from Lake Hood to a remote state park cabin at Klutina Lake near the mouth of the Mahlo River, northeast of Valdez. While exploring the marshy mouth of the river for wilderness photography, they were unsettled by a long, mournful, and sorrowful howl echoing through the tall grass. That night, while sitting outside, they observed a powerful, anomalous bright light across the lake that rapidly dimmed and performed an oblong, figure-eight tracking motion up and down the beach.
