The speaker for the meeting this month was great. He was the assistant principal at Canutillo High School. He spoke on the geology of the Organ Mountains just east of Las Cruces, New Mexico.
-
He was a good speaker, and he really knew what he was talking about.
-
Through him I met a Freshman at Canutillo High. He and his dad run a small business importing minerals from Mexico. I went over to their place yesterday evening.
-
I was really pleased. They had a good selection of fluorescent calcite and aragonite (polymorphs) which both have the chemical formula of calcium carbonate but different crystal lattice structures. This is a close up picture of some calcite crystals from Chihuahua which have phantoms in them.
