Binkley-Ober Quarry, East Petersburg, PA - November 13, 2004

On November 13, 2004, 10 mineral collectors braved the cold windy conditions to visit the Binkley-Ober Quarry in East Petersburg.  Once again, this was the first DMS trip into this quarry in a number of years.  This is also an active quarry that mines the limestone, dolostone, shale and sandstone of the Cambrian age Buffalo Springs Fm. for road aggregate and cinder blocks

The group included 9 DMS members (Joe Meloney, Ken Casey, Tim Cretien, John Osoinach, Karissa Hendershot, Carl Muendel, Jeff Chalfant, Tom Pankratz and me) along with Jim Schoonmacker from the MGS.

The most notable find of the day was made by Joe Meloney, whose very nice specimen of pink dolomite is pictured on the DMS web site.

All of us came out of the quarry with numerous specimens containing calcite crystals, pink dolomite crystals, and purple fluorite and had a good time while collecting them!
