In the facinating world of geology, one never knows what lurks under the next rock or just inside an abandoned silver mine. Geologist Javier Garcia-Guinea put his head inside an opening of an old silver mine in Almeria, Andalusia, Spain in June 2000 and found a gigantic geode, covered with large crystals of gypsum of exceptional transparency. The chamber measured eight meters long, 1.8 wide and 1.7 high. Courtesy/unique-almeria.com

This meeting will be a potluck and silent auction with the main entrée provided by El Parasol.

The Los Alamos Geological Society June field trip is set for the Nacimiento Mine about six miles east of Cuba.

For this trip, participants will meet at 6:50 a.m., Saturday June 23 in Sullivan Field parking lot.

And remember, just as that unsuspecting geologist stumbled across a gigantic geode in that old silver mine in Almeria … something incredible may be awaiting discovery just inside the Nacimiento Mine.
