We didn’t find any Yooperlites last night but we had a late start after having a big fish fry.
We will try again tonight.
We were out looking at a few good areas this morning…
Yooperlite / Sodalite : sodalite-bearing syenite source of this material is located in Canada, specifically the Coldwell Alkaline Complex in Ontario, and that fragments of this complex were transported to their approximate present-day location by continental glaciation, further slightly moved, concentrated, and somewhat wave-polished by modern Lake Superior. Indeed, the presence of minor orange-red natrolite (alteration of nepheline) in these clasts argues strongly for a Coldwell Complex origin (Mitchell and Platt, 1982).

Origins :
So cool! They look other worldly for sure. I love the great Lakes!
These rocks sell for $60-$100 a piece. So we are hoping we find some to sell here on the Blurt Market.
That is awesome! I could see how people would want them
Amazing rocks.
