The 2002 flood released approximately 67,000 cubic feet of water per second, which is roughly equivalent to the flow of Niagara Falls at its peak.
Exposed rock layers within the gorge contain fossilized ammonites and rudist clams from the time the area was covered by an inland sea.
The gorge floor is comprised of massive limestone slabs that were moved and repositioned by the raw power of the floodwater.
Significant fault lines visible in the gorge walls demonstrate the seismic history of the Texas Hill Country.
The site features natural 'potholes' or circular depressions created by swirling debris and water cavitation during the flooding event.
Canyon Lake Gorge is a 64-acre geological site created by a catastrophic flood event in 2002 that exposed limestone layers spanning 100 million years. The gorge was carved when record rainfall forced water over the Canyon Lake spillway, stripping away soil and vegetation to reveal Cretaceous-era rock formations. The site features exposed faults, ancient fossils, and dynamic water pools. It serves as a living laboratory for geologists and researchers studying the power of erosion. Visitors access the area through guided tours managed by the Guadalupe-Blanco River Authority. The landscape shifts from sheer vertical cliffs to sprawling, rock-strewn creek beds.

Wear sturdy, closed-toe hiking boots with excellent traction as the terrain consists of loose, uneven limestone rocks.
Bring a refillable water bottle, as the gorge traps heat and offers very limited shade during the summer months.
Apply sunscreen and insect repellent before beginning your tour, as you will be exposed to the elements for the duration of the visit.
Attempting to visit without a pre-booked guided tour, as the site is not open for independent exploration.
Tours are weather-dependent and may be suspended during heavy rain or high-flow conditions; check the website for seasonal tour availability.
Strictly pack-in, pack-out policy; do not remove or disturb fossils, rocks, or plants; stay on designated tour paths.
