Triangles on Tree, and other trees to ID

[RetrieveIt]

This is my last post of today, new to this hobby/newjob/lifeforce
I am wondering if there are any tree markers in these photos or altered trees? Any input is appreciated

Looks like natrural tree growth to me. Birches and poplars grow with those chevrons where small branches were. Holes are from damage that healed up.

Thank you for all your help today!! Tomorrow I will be going to an area of these 15 acres of woods that had a house on a 1907 map that wasn't there in the 1919 map!!
