September 10: Penn-MD Quarry

We have been invited by Joe Marchesani, president of the Pennsylvania Chapter of the Friends of Mineralogy to join them on a field collecting trip to the Haines & Kibblhouse Penn / MD quarry.   I've been unsuccessfully trying to get us into this quarry for several years, so thanks ever so much Joe !
The trip is set for Saturday, Sept 10 starting at 9:00am.
If you are interested in attending this trip you must email Joe at:   Email me also:
The trip is limited to 40 people on a first come, first serve basis.

Please note, all field trips are weather permitting, and are subject to last hour cancellations.
Our Chapter has a field trip set for 9:00 a.m. Saturday September 10 at The H&K Group’s Penn/Maryland Materials Quarry, Peach Bottom, Lancaster County, PA. This quarry is extremely close to, with similar geology and mineralogy to, the Cedar Hill Quarry (Stoltzfuss Quarry of decades past) on which more has been published. Both are in the State Line Chromite District.

Signing up with Joe Marchesani is required - e-mail
Provide the name of each person in your group. No children - all those attending must be at least 18 years of age. Joe will e mail a response saying you are confirmed to attend. For possible sign-up by text, see article at right.

The trip is limited to 40 FM-Pa members. If you have signed up and later find that you will not attend, contact Joe as soon as possible and tell him, so that someone on the waiting list can go. Please DO NOT BE A NO-SHOW.

On Saturday September 10 2016, confirmed attendees meet at the quarry by 9:00 a.m.

Safety protocols: each person MUST HAVE a hard hat (manufacture date no older than 3 years), safety boots, safety glasses, safety visibility vest, and gloves; and stay alert and use caution and common sense while on the property. No children under 18 years of age.

Here's our DMS Field Trip t from our last visit there in 2011

DMS Field Trip Report
Haines&Kibblehouse Penn/MD Quarry
We met at the quarry office at 8 am, though Joe and I were there a bit earlier so our host, Chris Adams, showed us photos of some of the fine minerals found at the Penn/MD quarry.  We asked him if he knew of any recent good finds and he mentioned zircon crystals at a particular outcrop but wasn’t so sure we’d be able to get to it. 

After a little while, Bob, Jose and Bill arrived and Joe showed them the photos.  A few minutes later Donna showed up and we all went to the office for our safety orientation: hardhats, safety glasses and stay behind the berms as the faces are highly unstable.  Other than that, we had free roam of the quarry.

The Penn/MD quarry is pretty big, being about 1/3 mile in diameter and 4 tiers deep.  It’s primarily a crushed stone quarry and the majority of minerals are in the serpentine family.

Chris led us down into the quarry and turned us loose.  Joe and I immediately went to the zircon area and Chris joined us.  It wasn’t safe enough to get up to the main seam, but a fair amount of material had washed down.  Chris picked up a clod, broke it open and in a few seconds found a zircon crystal.  The crystals are quite small most being in the 1 to 2 mm range and a clear honey brown in color.  Joe and I decided against searching for the zircons on site and each loaded up a flat of ‘black zircon’ mud.  I brought about a 5 gallon bucket full home and panned 9 g of zircon crystals, the largest was 6mm.  I’ll bring a vial of crystals to the October meeting.

We joined the others who by now had scattered throughout the quarry.  Though we all searched for crystals and pockets, I don’t think any of us had much success.  There was very little hammering.  I think most of us picked up a variety of serpentine rocks that caught our fancy for one reason or another; color, shape, patterns, whatever.

I think the best find of the day was made by Bill Stephens.  He found a rather extensive outcrop/pocket of chalcedony that was both colorful and translucent and collected close to 200 lbs.  Some of it has a carnelian color, a pocket wall texture and covered with druzy quartz crystals.  It’s quite pretty.  I’ll bring a piece to the Oct. meeting.

And I’ve asked the other participants of bring a favorite piece or two from the days collecting.
We called it a day at noon, and thanked Chris for hosting us on this enjoyable field collecting trip at the Haines & Kibblehouse Penn/MD quarry.

Don't hesitate to contact me if you have any questions,
