Mission Tejas Geology 101!
Fri, July 24, 2026
Come to Mission Tejas for a crash course on Rocks 101!
Mission Tejas State Park is a good place in East Texas to have an introduction to the wide world of the study of rocks and their millions-of-years-long cycles.
We will meet at the Visitor Center and inspect different stone samples and go over the basics of rock ID and uses. Afterwards, visitors can take a relatively easy self-guided hike starting at the Commemorative Mission to the Hardwood Trail and get a look at the Weches Eocene Formation; a unique rock strata dating back from 56- to just under 34-million years ago. This strata is known for its high iron levels and marine fossils from East TX and Louisiana's time being submerged under water.
Where: We will meet at the park Visitor Center; restrooms available.
When: July 24 @ 2 PM.
Cost: Regular admission into the park: $4/person. Children 12 and under (and carriers of a valid Texas State Parks Pass) get in for free!
