I think you're confusing them with geodes dug out of Shuteye Peak that were used to power the time machine. But it was called Shuteye because there was a cave somewhere around there where the Indians slept overnight on their commute to Granite Creek, and then over Mammoth Pass. I thought a Mimieux was a double gauss French lens put on leatherette-coated Yvette folding 127 cameras. Were they really that bad?
