Howdy folks,
Here's the second bunch of examples of the rough to be found in Rio Grande gravels down at Eagle Pass. The cool thing about this rough is it's been river tumbled enough to remove most the junk. The bad thing is the rough runs in sized mostly too big for my ten inch saw. The average pieces are five pounds or more. Most these are agate varieties and believe me, these are just a few of the types to be found. Thanks for looking.....Mel
Typical agate nodules. Some are banded and some are Montana type. The one on the left here is a tube agate and on the right, plume.
Flower Garden type agate:
These examples are orbicular agate or poppy jasper. Very hard material.
My favorite type of moss from this location, red of course.
The most common color of moss, gold or as my buddy says, "Baby Crap Yellow" this comes with fortifications, so dense as to be more like jasper or with very loose patterns.
Odd moss, only find a little of this. here the moss is almost sagenitic forming pom poms in the agate but not true pom pom agate like you find at Needle Peak.
Another fairly abundant type that looks very much like Roostertail Agate.
Weird banded and a swirled rhyolite or rhyolite and agate mix. Ranges from fairly porous and soft to hard as tacks.
And finally, this material comes in a huge variety of types. I guess you'd classify it as chert. It has colorful cloudy patterns and is about the hardest material I find. Really tough on saw blades.

Hope you'll please post a pic of some Devils Toenails if you have some of 'em.
