Strange Bigfoot Activity Discovered on Owner's Land

A property owner explores their land and documents several unusual findings: a large axe-shaped impression in the ground, what appears to be a footprint, mysterious wood knocking sounds heard in the distance, a large tree mysteriously laid out in the middle of a field with mushrooms growing on it, and tree structures built on a hillside that appear to have been deliberately constructed. The narrator notes these items weren't there recently and expresses amazement at the discoveries, wondering about the cause of the activity on their property.
