Canyon Lake Gorge
Canyon Lake Gorge is a limestone gorge around 1 mile long, hundreds of yards wide, and up to 50 feet or more deep. It was exposed in 2002 when extensive flooding of the Guadalupe River led to a huge amount of water going over the spillway from Canyon Lake reservoir and removing the sediment from the gorge. The gorge provides a valuable exposure of rock strata as old as 111 million years showing fossils and a set of dinosaur tracks, and forms a new ecosystem for wildlife with carp and other creatures in a series of pools fed by springs and waterfalls. -from Wikipedia
