I agree, it looks a lot like the stuff in the Black Hills.
Hill city has got a pretty decent brewery on site. Stopped there a couple times. They also have a winery next-door, the wines are just OK.
I feel like the stuff at the Nebraska National Forest would be a good extra day tag on to the Black Hills trip I’m trying to get organized for 2023. It would be a great place to camp and you could spend all day riding trails. Then after we would pack up camp and drive out, the Black Hills aren’t that far away for the rest of the time we would be riding.
Now I just need to find a good loop in the hills that would last three or so days
