Yeah that’s a typical sasquatch, twist break, that has healed, probably done when it was smaller, but I have seen trees 5-6 inches thick with fresh twist breaks, they do LST better than me lol. Nice find on the footprint, shame the sand was wet, with better definition you could have made a plaster cast. You can definitely see toes on it though.
The x block on the path is typical squatch as well, did you see any TP type structures in the area?
Edit for an add. looking at the foot print, it cant be human, squatch have a midtarsal break in their feet, unlike humans, They push from a different position on the foot. Found a pic.
They use twist breaks on trails to mark territory from other clans. The direction of the break indicates the opposing groups side of the territory. The same for X trees being a no go area. If that is on a trail then it could well be a hide for ambushing deer, bear or other game as well as a demarcation point. If you ever go back there see if you can find any hair on the branches of that twist break/hide.
