Sage Wall in Montana??....

I didn't know where else to place this post and if I've been mislead by false information, please feel free to delete this post.  I just came across mention of a natural ancient stone build called the 'Sage Wall'.  It appears to be on private land and I've not been able to find much more by general internet searches (see link below).  I'm fascinated by finds like this that are quite large, yet somehow outside of the public eye and knowledge.  In an odd way, its existence has reminded me of the short story by F. Scott Fitzgerald titled "The Diamond as Big as the Ritz", a surreal tale set in remote mountains of Montana.  Anyway, as the hub of Permies.com is near Missoula, I was hoping someone more knowledgeable on the structure might have links or information on the archaeology of this site and it's general location.  Fascinating if it truly has only been discovered relatively recently....or just made public in recent years??  Thanks!....

Wow, that is neat. Going down the rabbit hole to read some of the hypotheses on how it came to be...

...and popping back up after seeing a couple of sites insisting it was manmade, complete with fake pictures (Inca wall effects). It really does look like a weathered granitic intrusion to me. If it had been basalt the fractures would have created hexagonal columns. Rhyolite does a similar thing with more layering. The mountains of SE AZ have lots of rock gardens with similar formations and that stacked block effect is definitely a theme I saw a lot of in my decades of hiking and exploring that region.

Interesting...and much thanks, Phil, for the comments.  Yes, I've seen basalt columns a fair amount in drives from western Oregon to Idaho and recall the hexagonal features.  The photos of the Sage Wall instantly reminded me of photos that my wife has of Machu Picchu in Peru which were man-made.  So I jumped to that possibility.  But as you noted, several others have invoked  geological forces to explain the formations along with your own observations.  Even as a natural phenomenon, I was surprised to have never heard of this wall on past travels through the state, but if it's been on private land, that would explain it.  Thanks!
