October 28, 2006, Saturday: Teeter Quarry, Gettysburg, PA : This active quarry mines traprock and hornfels.  Minerals that have been found at the quarry include: stilbite, heulandite, laumonite, epidote, chabazite, chalcoite, malachite, iridescent bornite and garnets.  This quarry also produces some cutting material.  DMS members will be allowed to collect in the quarry from from 8AM - Noon.  

Afterwards, I invite you to attend the South Mountain Rock Swap at the South Mountain Fairgrounds ~1.5 miles west of Arendtsvilled, PA on route 234.  The swap runs till 3:00PM and costs $1. to get in.  Last year, several of us stopped by the swap after collecting at Teeter Quarry and found some very nice mineral specimens and lapidary material at very reasonable prices.

Teeter Quarry, Gettysburg, PA - October 30, 2004

On October 30, 2004, 10 dedicated mineral collectors braved the inclement weather and visited the Teeter Quarry in Gettysburg.  This was the first DMS trip in a number of years into this active quarry, which mines traprock and hornfels for road aggregate.  The group included 9 DMS members (Joe Meloney, Ken Casey, Ed Murphy, John Osoinach, Karissa Hendershot and her father, Fred Hendershot, Jeff Chalfant, Eric Hottenstein and yours truly) along with 1 guest from the Maryland Geological Society (MGS), Jim Schoonmacker.

The most notable finds of the day were made by Ed Murphy, who spent most of his time reducing one large boulder into smaller pieces of pink as well as white Stilbite and Joe Meloney who found a nice specimen of chabazite.
