Generalanalcite

On Terlingua Ranch is a very, very short section (just a few feet long) in a dike that is an zone of small cavities containing perfect analcite crystal which are less than 1mm in size. It really requires a microscope / loupe to view the crystals. I discovered this locality in the very early 90's. There was not much in way of material to begin with, so I may have collected all that was available.

There is no prior description of this locality as far as I know. Why do you ask? It is really out of the way on Terlingua Ranch.

As Bob said, I'm not suggesting that every time someone finds a small calcite crystal in a road cut that they need to alert the media. In this case analcime is certainly known from Brewster County ( https://www.mindat.org/locentries.php?p=16765&m=210 ), but it's relatively uncommon so it may be noteworthy to expand the known distribution in the area.

I'll try to add a photo or two of the analcite crystals when I have a chance.

I know of yet another locality with a huge amount of small pockets of zeolites (again, the overall length in feet of deposition is small). The problem is finding someone who can do the x-ray diffraction work. The variety of minerals is seeming high, but the crystal size is small to very tiny.

Probably from the 70's, Texas became an extremely difficult place to collect. You couldn't get into the oil (and sulfur) fields around salt domes and general collecting in the State became very difficult. Going to West Texas was at least a 500 mile drive and the collecting was nearer and better in Arkansas (he was a funding member of the Coon Creek group).
He was an active bibliophile, developing the Houston club's library.

If listing all the places one visited is proof of extensive collecting, damn, I've collected in Pennsylvania, North Carolina, Alabama, Mississippi, Louisiana, Arkansas, Missouri, Texas, New Mexico, old Mexico, Arizona, Colorado, California, Utah, Nevada, California, Oregon, Washington, South Dakota, etc.
I guess I need to write about each experience so I can be credited with being known as an extensive collector. I can tell you right now that in one or two years I collected more in Arkansas than Art did over the years and years that I knew him. He made that Coon Creek trip it seems like every year to Arkansas, but that was it. I don't recall him ever making a trip to Tucson for the mineral show. Maybe he did before I knew him. He never showed any minerals he collected / bought at the HGMS club mineral meetings.

I need to check Sul Ross re diffraction ability. Frankly, I want to go back to collect more specimens before releasing the locality to the general public because I am sure that would end collecting there or it would be collected out. It is a long-ish trip, but can be made in a day easily from here in Houston.

He bequeathed his collection to Wheaton University. It was a total of 30,000 specimens of which 20,000 were micromounts.

He bequeathed his collection to WHEATON COLLEGE (not university). A religious institution of very hi standing, but otherwise a rather odd place as their views on creationism and evolution don't matchup with most of our scientific geological views.
