Tree structures are found throughout Alaska's Boreal and Sub-Boreal Forested areas. They're often attributed to Sasquatch behavior by many researchers. Some of the structures can easily be explained due to extreme weather, natural rot, or disease (Alberta Sasquatch, 2018). However, some structures appear too complex to be random acts of nature. These include large diameter trees broken from their roots and set in place. Other features show a pattern of construction including appearing to be "woven" in place.
There can be multiple possible meanings to the structure including marks of aggression, territorial boundaries, hunting blinds or ambush sites. Some of the structures resemble crude shelters suggesting short term use. Some Native American and First Nation Elders have eve suggested some tree structures could also commemorate the birth of a new member of a Sasquatch family (Alberta Sasquatch, 2018).
Tree structures are not positive proof of Sasquatch activity or even of its existence, but they sure are interesting.
