Archeologists have found evidence at the San Marcos River associated with the Clovis culture, which suggests that the river has been the site of human habitation for more than 10,000 years. The San Marcos Springs are the third-largest collection of springs in Texas. Never in recorded history has the river run dry. In 1689, Spaniard Alonso de Leon led an expedition from Mexico to explore Texas and establish missions and presidios in the region. De Leon's party helped blaze the Camino Real (later known as the Old San Antonio Road), which followed present-day Hunter Road, Hopkins Street, and Aquarena Springs Drive (the route later shifted four miles to the south; it is now followed by County Road 266, known locally as Old Bastrop Highway).
