In South and Central Texas, there are many remnants of marine volcanos that were present in the shallow seas about 80 million years ago. An example is Pilot Knob in Travis County and there are many others near Uvalde,” McCall said. Pilot Knob is the closest volcano to San Antonio, just a few miles outside McKinney Falls State Park near Austin.
