Scenic

Further along the Iron Mountain Road (through Custer State Park)there are three of these tunnels cut through granite ridges, all of them sited such that they point the traveler towards Mt. Rushmore.

Interesting Friday at work. That is all.

Granite is a bitch to tunnel through. They did a lot of this with jackhammers and drills
