On December 27th, a tanker loaded with over 9,000 gallons of liquefied propane failed to negotiate a curve near the park and overturned, killing the driver. The accident closed state highway FM 652 for over 30 hours while a hazmat team removed the propane. The park provided personnel, equipment and technical expertise to the response operation. Low temperatures, winds over 60 mph and the remote location hampered the response. The accident is under investigation by the Texas Highway Patrol.
