Exploring Bullet Cave in Austin, Texas with Michael Mixerr again.

Bullet Cave is one of the “more hidden caves” of Austin/Travis County which local cavers, spelunkers, and climbers know about. This news article will explain the biology and geology behind Bullet Cave.

 


Bullet Cave is just a 10 minute hike from the parking lot at the Loop 360 entrance to the Barton Creek Greenbelt. It’s not difficult or very long, but it's a great initial exposure to caving in Austin and it gets you into near total darkness. Only thing is that it’s just about a 40-foot crawl.

A cliffside cave called Bullet Cave is visible to the naked eyes from a far distance from Barton Creek in Gus Fruh Park and Barton Creek Preserve. Bullet Cave is located on a cliffside called The Flats which is located above Barton Creek. The cave is a crawlway about 30 feet long and is about 65 feet above creek level. The crawlway inside this cave is about 75 feet long in diameter.

 

Bullet Cave is difficult to enter to due to the location being on the wall of a cliff and the steep rugged terrain that is on a 55º degree angle. The high distance above ground makes accessibility difficult for many people. Even cavers have a hard time climbing to get into Bullet Cave. To access this cave, you need to climb a steep slope that is located on a hillside. The length of this steep slope is 43 feet long. There are huge boulders which make accessibility towards getting to Bullet Cave difficult. Navigating through these boulders can be quite challenging.

One you reach the outside of this cave, you will be able to see a beautiful view of Barton Creek and Gus Fruh Park itself. The view from looking outside this cave is similar to an aerial view. You will be surrounded by a view of trees and cliffs. And also houses, apartment complexes, and businesses.

A sense of moisture can be felt inside of the cave. Sometimes on hot summer days, a sense of arid dryness can be felt inside of the cave. However that is ultimately rare as this cave is near a creek.

Now the rock formation of this cave is native limestone. Many caves in Central Texas have a rock formation of native limestone. Raw iron ore can be found outside rims of this cave. Iron ore is the most common natural element found in this cave. So is limestone. (Ref: https://explorersguide.org/barton-creek-greenbelt/)

Bullet Cave is located just less than 20 feet away from Hobo Cave which is located in the same vicinity as both of these caves are located in Gus Fruh Park and Barton Creek Preserve. Bullet Cave is considered to be inside Barton Creek Preserve.

Michael Mixerr of Mixerr Reviews explored Bullet Cave in Gus Fruh Park while during a caving outing. Michael Mixerr witness the unsettling sight of destruction. “Upon entry of this cliffside cave, I come to find signs of vandalism such as graffiti and litter. Several graffiti markings can be found inside of this cave. Several beer cans were found scattered on the ground inside this cave. So people have used this cave for partying.”


 

A sense of moisture can be felt inside of the cave. Sometimes on hot summer days, a sense of arid dryness can be felt inside of the cave. However that is ultimately rare as this cave is near a creek. The entry is more arid than the inside. 

 

“Upon entering Bullet Cave, I felt a sense of moisture the first 10 seconds I was down there. You can feel a sense of moisture down in that particular cave. As you get further into the cave, you can feel a sense of dryness. There is no moisture or humidity at the end of this cave,” said Michael Mixerr.

Bullet Cave is located just below a single story house that is located at the address of 1802 Glencliff Drive, Austin, Texas, US 78704.
