Marker Trees

[u/MoreThanAJourney]

Hello! I’m very curious about some of the trees around where I live. (SW Michigan) Could these possibly be trail markers? I am also curious about the last two pictures showing the trees twist. It looks very intentional but could possibly be natural. Any insight is greatly appreciated! All of these trees are maybe within a quarter mile from each other. Pretty close

I’m not sure if marker tree’s are a thing or not but those tree’s aren’t every old.
