This marker was found about 20 feet from the crisscross spot, If I had to Guess I would say it is an owl.
Owl with tail pointing to right. These are pretty good at pointing the direction to something else of importance. I found one about a foot and a half long and half buried in the ground. Right next to it, half buried, was a brass survey marker with Minnesota Surveying Company embossed on it. Probably just a coincidence. I carefully rolled the rock over to see if there was any information under it. The contour of the bottom of the rock was identical to the terrain to the next marker, over 400 yards away. It was cool. I guess the shaping of the bottom of the rock was meant to be some kind of confirmation that you were going in the right direction. What was the tail pointing to on your owl?
