Texas Rockhound Locations

Texas is a great place to start your rock-hounding journey. The plains regions have several varieties of limestone, shale, and fossils. The Western region hosts several varieties of igneous and metamorphic rocks, which is perfect for the gem hunter. 

Why is Texas such a great palace to hunt for gems? Where should you start your search? Here are some of the best rock hound locations in Texas! 

Texas has various agates, jaspers, fossils, geodes, and petrified wood. 

The best rockhound locations in Texas can be broken down based on the types of rocks you want to find. Check out this color-coded map to get an excellent overview of where to find sedimentary, igneous, and metamorphic rock.

Texas was one of the most geographically active states in the U.S. over several million years. 

I’ve broken down these ages and their geographic activities below: 

  • Precambrian Period: Texas was experiencing flooding and probably emerged from the seas around 1 billion years ago. This created a large deposit of sediment.
  • Cambrian Period: A shallow sea covered the surface of the state. This brought a heavy deposit of sand and various small sea creatures. 
  • Ordovician Period: Shallow seas started to recede, but certain areas were still submerged. This left hard deposits of limestone and dolostone on cliff sides.  
  • Permian Period: Skipping ahead a few ages, the Permian period was one of the first times Texas lost most of its shallow seas. This means Texas is a great state to dig for Trilobites
  • The Cretaceous: Texas experienced several periods of flooding and shallow seas. These seas left large quantities of mineral and fossil deposits all over the southeast and southwest of the state
  • Quaternary Period (Pleistocene): This was towards the end of the glacial periods when great ice sheets began to recede.

Is it Legal to Collect Rocks In Texas? 

It is legal to collect rocks in most parts of Texas. However, you must be careful to avoid trespassing on private property and oil fields. Texas is a resource-rich region of the U.S.; some of the lands are protected property and do not permit exploration.


Where Can You Find Geodes in Texas? 

Geodes are a somewhat prevalent crystal in Texas. Central Texas and the Edwards Plateau are the best places to start your search. More than likely the geode will be filled with Calcite or Quartz.
