Account

The witness was hiking alone and stopped for water when loud wood knocking lasting 10-15 seconds was heard. The witness made phone recordings that captured one loud knock plus fainter knocks believed to come from three locations. The witness continued hiking and returned later without further sightings or sounds, noting no other people were nearby due to winter closures.
