Re: Please help me identify a central Minnesota rock
If the photo I saw was correct, it looks like orbicular jasper. There is also a variety of Lakers called eye agates. Some of them have a ton of little orbs like the jasper and have the red-orange-yellow banding like Lake Superior agates around them. I cannot tell from the pic, but maybe a quick search on the Googlesphere may help. Good luck!
