about a week ago I bought an app that identifies rocks... no, not music, rocks. Not sure how accurate it is and since I have next to zero education regarding rocks I'm not sure if I'll ever know.

BUT... seemed fun. My mountain ranch is known as a rockhounds paradise. Even some gems to be had. My oldest grandson is interested so we're planning a trip... follow the creek, look for bedrock, then start picking and identifying. Who knows? May happen on something valuable.

So sorry for semi-hijacking your thread... just struck me funny how at first glance I thought you had stumbled on a topic that at this precise time I'm about to explore. - JamesJM
