looks like someone dug a cave at the base of the rock.

I was about a mile from the NW rim of Horseshoe Canyon about 60 miles south of Green River and maybe 30 miles NW of the confluence of the Green and Colorado rivers. There was a ranger station about 10 miles further south of me and a dirt road that headed west to a paved highway 20 miles away.

I found this domed rock about a mile west of the first entry point for the Canyon that had all these lines running over it, little ridges maybe 3-6 mm high and curved in long arcs. The rock was 8-10 ft wide and 18-22 ft long and maybe 4 ft high and a bunch of the lines met at a sight hole near the top of the rock on the left, the hole lined up on the SE just above the horizon and appeared to be used for lining up a celestial object.

Two deep parallel grooves were cut across the rock pointing south. I stood behind the rock looking south along the grooves and didn't notice anything unusual, then I looked thru binoculars. And WOW, I could see a line across the valley stretching about a mile to the southern horizon. It was like somebody had walked straight south from the rock so much a path was beaten into the ground but there was no path that I could see. Even vegetation was different, the coloring enhanced the image of a line somehow. I have pictures of the rock but dont know how to upload them, but you cant see the line extending south from the rock. It only shows up with telescopic vision.

I'd love to know what they were looking at thru the rock and how and why the terrain hides that line going south. I'm reminded of the satellite imagery of the Chaco complex to the SE, ancient trails beaten into the landscape heading in different directions but undetected at ground level.

I could spend a year out there easy looking at stuff
