There are so many responses I have here to other posts.... and though I feel like I am in the minority, I am still compelled to reply...
I guess the short of it is that I stand for private property rights.
It is private land, and whether the soil is touched or not, part of the persons body is over the private land. That right, title and interest contained in a deed includes the 'air' above the corner (maybe not to the sky, but at least above what you and I can step over).
Secondly... if touching the ground is the basis of it not being illegal.... scenario: there is public access to the public property from another way, and I see a legal elk over there... then can I shoot over the corner when the elk is on the kiity-corner property? Does a bullet (or arrow) constitute corner crossing? (It is not touching the ground on private property).
Third (and quite possibly the MOST important)... just because something shows to be a 4 way corner on a 7.5 minute quad map or some other F&G map (or even worse, OnX / Google Earth) does not mean that those corners meet. The hunter needs to be sure that it is actually a common corner. Only one way to do that... read the deed. And you may need to read all 4 of the deeds (at least 2).
Fourth... We all think of a fence at a corner, which most of us can climb over. But the private owner has the right to build a concrete wall at his corner as well. That wall can go up to the property line. That wall can be as tall as he plausibly wants. The footing should be on his private property but even for the construction of said wall, he can be on the adjoining property because he is part of the public that does have right to that land. That wall removes your ability to physically corner cross, AND that wall is completely on private property. If that wall that is entirely on his property would impede you from corner crossing? How can someone say that not touching the ground is what allows corner crossing? Is it just because the private owner has not built a wall and his kitty-corner neighbor hasn't built a wall?
