"Lake Superior Agates were once plentiful on the beaches of along the Lake Superior, but, it is a good day if a nice one is found at present. Best hunting is right after a storm or de-icing in the spring. Where to hunt for these gorgous stones? I would say just about any beach that has pebbles on the South, east and West shores of Lake Superior should all be combed.
There are many beaches where they may be found here in the Upper Great Lakes regions, as well as a number of ridges where they can be dug from the ground at the base of the ridge or removed from the basalt such as quarries. Although this is hard work and not many people care to do it. "
