Singleton Ranch Black Plume Agate'

South of Marfa Texas you'll find the Singleton Ranch that has been a hotbed for collecting agates for many years but just last year in 2014 the owners of the ranch started scheduling field trips for collecting. Up until now they wouldn't allow any collecting. Awesome news! Here's a slab from one of the finds from a recent visit. -WET pics.-(4"x 2"/1.4 oz./4mm thk) no fractures.
