Sage Wall is nestled in the Pipestone area of the Boulder Batholith. Known for amazing rock sculptures that seem almost man made. On our visit to Sage Mountain Center (Link Below) we found a warming host and an amazingly cleaned up trail and of course their Sage Wall. While everything was cleaned up so nicely it was hard not to imagine this was man made, it resembled the walls you might see in South America. If it had not been so well maintained I would have walked right by paying no attention. Also, the idea that this wall could serve any purpose is one of the main arguments against the Montana Megathilths being any more than pareidolia. They serve no purpose. This "wall" can be found on every ridge line in the area. We were able to see them on the way out. We even met someone with a "wall" on their property in their own backyard!
