I went on a field trip last weekend with the
Hays County Master Naturalists to the “
Cave Without a Name” near Boerne. The cave is recognized as a National Natural Landmark.
The tour sizes are limited to 25 people and there was so much interest from our chapter that we had to split into 2 groups. Each group spent an enjoyable 90 minutes, in a constant 66 degrees, touring the 6 major rooms.
The guide explained how the cave was formed by underground flows from the nearby Guadalupe River and how the various formations (
speleothems) including stalactites, stalagmites, columns, curtains, and other features are created.
Here's an
ammonite fossil at the entrance to the cave. It's almost two feet in diameter.
Here's a fried egg formation, about 6 inches across.
The cave had many intricate and beautiful formations.
It also had several cave pool formations.
Our part of Texas is peppered with caves because of the geology. Most of them are probably undiscovered and most of the known ones are on private land. The Cave Without A Name is a nice one and it's make a nice day trip from anywhere in Central Texas.
