We are up in Grand Marias in the upper peninsula of Michigan. A friend found this rock on the shore of Lake Superior. The rock is photo sensitive to UV light. After being exposed to the light from a VU flashlight it will continue to glow for a second or two. Anyone know what this is?
I have a short video of it but I don?t have a third party site to upload it to.
