CUSTOMER AGATE FINDS
March 2013
Since the museum has not been open, I only have one set of actual customer agate photos. Chris Cooper showed me the raw agate last summer that he physically extracted from basaltic rock in the Keweenaw Peninsula. Since this agate nodule had never been subjected to erosional forces (e.g. waves, ice, etc.). Notice how there is a full husk on this agate and that absolutely none of the chalcedony is showing on the outside. Keep in mind that this is rare and almost never happens with agates found on the beach, which have been subjected to erosional forces. Chris then tumbled the agate. Below are the before and after pictures.

For this month’s update, I’ll supplement this posting with some agate photos that I have taken, all of which are included in the Online Rockhounding Adventures. The next two photos show exposed banding on Lake Superior agates. The first one is a raw agate and the second is a polished agate.

Here are some more photos showing raw agates on the beach.
