Canyon Lake Gorge

rdf:langString Canyon Lake Gorge

rdf:langString Canyon Lake Gorge is a limestone gorge in Texas, which is around 1 mile (1.6 km) long, hundreds of yards (metres) wide, and up to 50 feet (15 m) or more deep, which 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. The Gorge Preservation Society formed as a local citizen's group to develop long-term plans for the Gorge in partnership with the Guadalupe-Blanco River Authority and the U.S. Army Corps of Engineers. Public access to the gorge is restricted to guided tours by the Society along a designated route for a hike lasting about three hours. Availability of tours is limited, no pets are permitted and no rock or fossil collecting is allowed. Research permits can be obtained by university or scientific research groups.
