Texas Underground

The idle monkey trainer took a short getaway in San Antonio, home of the Alamo, the Riverwalk, and a number of other historically important Spanish missions. Having thus spent Saturday, and with fond memories of a fantastic dinner at the Fig Tree restaurant, I ventured into the low hills and even lower caverns of the Texas Hill Country.

Completely ignorant of the many commercial and other caves of the Hill Country, I managed to locate the oldest commercially operated caverns in the area. Cascade Caverns is located at the end of the aptly and not coincidentally named Cascade Caverns Road off of I-10 about 20 minutes west of San Antonio.

The first occupants, or at least users, of the cave were the local Native Americans. They were famously followed by a German recluse who lived in the cave during the Texas independence movement. In the 1930's several buildings were built directly above the caverns, including the original owner's residence, which utilized a natural vent from the cavern about 100 feet below to help ventilate the house. These buildings, along with the caverns themselves, suffered severe flooding in 2002 and stand unused.


The caverns were named for the waterfall that helped form the caverns and can be seen at the end of the tour. (Above) During the 1940's the "cathedral" was used for religious services when the waterfall had dried up. Water started flowing again and the alter was removed after a few years of use.

The cavern floods often, and the operators run a pump every 45 minutes just to keep it dry enough to have visitors. The constant water flow keeps the cavern "alive" with a number of formations continually growing, like the below formation, which started following the 2002 flood.

In addition to human visitors, the cave is home to a unique species of salamander found only in this particular cave. Obviously with such a limited territory, it is an endangered species. They are also incredibly hard to spot. Fortunately the guide is sharp-eyed and knows what to look for. I certainly would have been unable to spot the two-inch, camouflaged little guy. This being Texas Hill Country, there are also a couple of resident bat species. (Not shown)

The caverns, and surrounding grounds, have over the years yielded a large number dinosaur fossils, including a mastodon tusk and femur embedded in the cave's floor and wall respectively. All of which goes some way to explaining the T-rex (currently under restoration) that guards the parking lot and entrance.

The final frontier



On the grounds of the Johnson Space Center in Houston, NASA has a small heard of cattle, managed by a local group.

I think we all know where this is going:
