The Llano Uplift, also known as the central mineral region, is an island of volcanic and metamorphic rock very different from the surrounding Edwards Plateau.
Containing 5,000 square miles, the uplift, restricted to Llano, Mason and adjacent counties, contains some of the oldest exposed rocks in Texas, including pink crystalline granit, schist and marble.
Geologically the region is a large dome with rolling to hilly topography. Granite exfoliation domes, the largest of which is known as Enchanted Rock, are common.
During their Spring raids, the Comanche Indians roamed from Palo Duro Canyon to the Gulf Coast and they passed through Mason County.
Many arrowheads and other artifacts are found.
Daniel and Crystal came from Houston and found this 20 gram 100 carat stone. It was not gem quality but Crystal was happy.
Both the Eastern and Western branches of Comanche Creek flow through the Lindsay Ranch. You'll mainly be looking through gravel in the creek for your treasures.
What does it cost? $15.00 per person for everyone 18 and over.
What do I need to bring? Simple tools, a rake, shovel, gloves, things that you would use in your garden. We have screens if you want to use them.
Is Topaz easy to find?
No it is not easy to find. If it was, everyone would have a lot of it. It is like looking for gold and diamonds but if you do find a topaz, you'll be very happy.
What else do I need to know?
Everyone who comes on the Lindsay Ranch is required to sign a Release of Claims and Waiver of Liability.
It says, in a whole bunch of legal words, that if anything happens to you, to anyone or anything you have with you, it's not my fault and you can't sue me.
Blue topaz is the big treasure in Mason County for gem and mineral collectors. Some blue pieces have been found on the Lindsay Ranch but most have been clear stones.
Topaz and quartz (including smoky quartz) can be found along the creeks in northern Mason County.
Most streams in the area run through the pegmatite-bearing granite where the topaz and quartz crystals were formed.
As the erosion processes wear it down, more and more of the gems are freed and deposited in streambeds, washes and other low-lying areas.
Topaz is the official Texas State Gemstone and the Lone Star Cut, named for the state slogan "Texas - The Lone Star State", is the official State Gemstone Cut of Texas.
The Lone Star Cut displays the familiar five-pointed Texas Star of the state seal.
This cut demands very precise cutting with particular attention paid to the meeting of angles, facet edges, and facet points so that the "star" virtually leaps out of the stone.
The most prized material for this cut is topaz that is mined in Texas.
