Yes, its likely a lake superior agate if you found it in that area. Agates tend to be associated with larger macrocrystals.
It's translucent but no color in the banding.
Please google banded agate and see for yourself.
There are no really distinct bands. I had already concluded it was an agate, I just wondered if that was possible. The only other one I found had different colored bands in a herring bone pattern.
If you look at the July/August issue of Rocks and Minerals Magazine, there is an article devoted to the agates of lake superior. See this link:
