Description

You are bidding on a small sample with some nice wulfenite crystals on yellow mimetite matrix from this very unusual and obscure South Dakota locality. Obtained in an exchange with Frank Tinsley by Dan in 1985. Comes with Dan's two original slides and his index card. Rare locality for wulfenite! 

This sample is from the collection of Dan Behnke, long-time friend, micromounter and prodigious photographer. I am pleased to be able to offer selections from his large collection, many of which are illustrated specimens in Rocks & Minerals, The Mineralogiocal Record, Photo Atlas of Minerals and many other publications. All samples from his meticulously catalogued collection will come with his original index card with all notes, photography annotations and other pertinent information, as well as any slides Dan may have taken of the sample with publication notes and date the photo was made.
