Bones, Stones and Drones of Maryland – Courtland Lee

Courtland LeeCourtland Lee is DCGIA’s resident Geologist and Miner, a geologist with an MS in Economic Geology from the University of Arizona (1967). After early work in western metals exploration, and a tour of duty in the U.S. Navy, Courtland went to work in Washington, D.C. on Federal Mineral programs.

While there he worked on Capitol Hill for the Mines and Mining Committee. Courtland was instrumental in getting petrified dinosaur bone “Patuxent River Stone” designated as the official Maryland State gemstone.


Courtland’s presentation provided insight into his pursuit of the Maryland House Bill 22 State Gem – Patuxent River Stone. The legislative roadmap was laid out as follows:
Have a Good Stone
Find a Legislative Champion
Draft the Bill
Testify at Hearings

Maryland Patuxent River Agate

The main competition was Williamsite – Emerald Green Serpentine.
A Green stone for a RED & GOLD State? Courtland did not think so!

WilliamsiteAdditionally, Courtland talked about Blue Ridge Native Copper, Maryland was a major American copper producer prior to the Civil War. Copper was required for both Civil War Bronze Field Artillery, and Copper Primers. As such Maryland was a resource rich state that the confederacy needed for the war.
