I am looking for classification of these two rocks I found on a recent trip to South Dakota. I am wondering if these are Fairburn Agates or something else. Any help would be appreciated!
Karen Brzys at the Agate and History Museum in Grand Marais MI has written a great book titled "Understanding and Finding Agates". It's my go-to reference guide.
