most likely the two vertical guges are from the brow tines i have seen deer do this many times. but on that 2nd pic posted.... i think that is a sign post rub...and we have one like that we put the trail cam on this fall and we had a couple small 1 1/2 yyear old bucks rubing and a big 14 pt. and a couple other 2 1/2..so i believe multiple deer are rubing that tree.
