The record — long form
Natural Bridge Caverns is the cave the students found — the biggest cavern in Texas, discovered March 27, 1960, when four St. Mary's University cavers crawled through a 60-foot debris-filled passage and came out into two miles of virgin chambers. Orion Knox was the first through; 'Hey, we may have something here' is the understatement of Texas caving.
The ranch knew about the bridge — the 60-foot limestone slab over the sinkhole had been there since the ceiling collapsed 5,000 years ago, and the farmers had known the small passages for fifty years. What nobody knew was what was behind the crawlway — the columns, the emerald pools, the soda straws, and the chambers that kept going for miles.
The cave is still growing — the Wuest family still owns it, still exploring, still finding new passages sixty years after Knox's crawl. The file keeps the discovery: the four students, the rancher's permission, the crawlspace that opened into the biggest cavern in Texas, and the cave that's still being explored.
Natural Bridge Caverns is the archive's discovery file — the 1960 student expedition, the crawl through the debris plug, and the Texas cavern that turned out to be the state's biggest.
Why this file matters
Natural Bridge is the archive's modern file — the cave found by college kids in 1960, the biggest system in Texas, and the family that's still exploring it.
A cave found by students keeps its crawlway — the file's suggestion being that Natural Bridge's hold is the squeeze: the 60-foot passage the kids dug through, the chambers on the other side, and the discovery that made a ranch into a cavern.
The Natural Bridge Caverns are the largest commercial caverns in the US state of Texas. The name is derived from the 60-foot (18 m) natural limestone slab bridge that spans the amphitheater setting of the cavern's entrance. The span was left suspended when a sinkhole collapsed below it. The caverns are located near the city of San Antonio, Texas, in the Texas Hill Country next to the Natural Bridge Wildlife Ranch, a drive-through wildlife safari park. The caverns feature several unique speleothems and other geological formations, including magnificent stalactites that hang from the ceiling . The temperature inside the cave is 70 °F (21 °C) year-round and the humidity rate is a constant 99 pe
