New state thread!

I've been collecting in Maryland for over a decade and this state continues to amaze me with its mineral wealth. I hope to post some recent finds soon.

I'll start with this quartz plate I found as float on a hillside on a job site of mine in Baltimore County.

Wow, that's a nice plate!  I assume you dug and found more there?

Yeah buddy, Scott, I did. Found the above specimen face up right beneath the trunk of a fallen tree. The root mass had loads of water clear xtals loose in the soil between the roots. They're small, up to an inch in length max, but they're Shingletrap lazers, and from this state to boot. I dug down and discovered a very shallow, very weathered, simple pegmatite d**e. The quartz xtals are in smoky veins in feldspar. Very little mica. Super cool to find quartz xtals growing directly on feldspar

Before I got into matrix specimens I was finding loose clusters in the A horizon organic soils. Lots of them like these:

Nice finds.  IIRC from the literature and a few older reports,  Baltimore County has lots of potential.

I have quartz from Howard county that is nearly identical to the crystals on the large plate ? Columbia Md. ,is crisscrossed with large quartz veins up to two feet thick. If you walk the green spaces in Columbia you will see  pieces of them near the streams I'd love to find out where the plate you have came from.
