Early Morning Howls Awaken Campers Near Liliwaup

28 August 2017 around 3:00-3:30 AM Liliwaup, Mason County, Washington 2 witnesses

Account

Two people camping overnight in hammocks were awakened around 3 a.m. by loud, long howls that they felt physically and that repeated several times from up the creek. They had never heard anything similar despite extensive wilderness experience and could not match it to known North American mammal sounds. They later found an online Sasquatch vocalization that sounded identical, but stated they did not know the source.
