First, here are some more of the "other" Lake Superior agates from John Marshall's presentation. When the images were flashing on the screen, I remember thinking that they looked like Tom Shearer photographs. Tom, as many of you know, was the photographer for my last agate book. Low and behold, Tom did take the photos.
