Sodalite in the Great Lakes area can be found on all the Great Lakes. The are from the alkaline complexes in Canada via glaciation. There is one over Lake Superior, Lake Erie, and Lake Ontario.
The alkaline complex in Arkansas has sodalite and I’ve collected about 100lbs down there.

Comments
I use all 3 UV lights: LW, MW, & SW.
If you’re referring to the sodalite, I use LWUV which is 365nm.
395nm is too low on the on UV spectrum to excite the electrons to fluoresce orange.
In the Great Lakes area, most rocks fluoresce under LW (365nm).
