Tonight the nephew FaceTimed me to help him with his geology homework of identifying different minerals. So fun!

Petoskey stones from Michigan.
My son collects and polishes some....I'll ask him

I have a piece of quartz that might weigh 20 lbs. I have been in other places with more interesting rocks. this isnt one of them

Wife collects rocks... I'm in Louisiana with rocks on my back porch from Arkansas...

My area is quite boring, there are a few small sites with semi precious stones. I too would love stromatolites, more for me, I was to go over and see them. One of the earliest life forms that are still around.

My Dad was into that. Have you ever heard of agate from Paintrock, Alabama? I assume that's what the town was named for. My Dad used to hike up in the hills and bring back 40 lbs. of it at a time.
