Sorry for the short intro post.
This is a Mesa in New Mexico. Private property that I have access to, but being that I am in Texas, not the time to search much.
The Mesa points in an NW direction and the mark is on the direct point (NW). The pic is taken looking south east. To the north is a plain, with salt flats. North of that (hours driving) is mountains. Mesa's and mountains to the west, a few small rises to the east. To the north east is a stand alone, saddle back Mesa.
This thing is big! Easily seen from the highway(2mi) and further. It stands out. Funny thing is I lived nearby for 10 years (as a kid) and never noticed it. Visible if your looking for it. My dad pointed it out to me a year ago. That's when I took the pic. Dad thinks it was a trail marker pointing towards the NE Mesa, which had springs.
We have found some camp sites around with arrowheads, pottery shards. Have found a couple of metates and manos, and only 1 bone bead.
I climbed up to the mark site looking for some sign of human interactions(tree stumps, flint shards). I didn't see anything, but didn't have much time(preggo wife waiting). The mark is on a sandstone outcrop and looked natural from onsite. From the distance it looks man made.
Hope this helps a bit.
