Sometime between 3 to 5 p.m., two people were seen on the south side of the summit of Enchanted Rock writing the words “CA$H TRUCK” on a rock, according to the Texas Parks and Wildlife Department.

Officials say the two people are from the San Marcos, Texas, area.

Park officials are asking anyone with information about the incident to call 830-685-3636 or to email Doug.Cochran@tpwd.texas.gov.

Enchanted Rock is situated in a 1,600 acre state park 17 miles north of Fredericksburg, Texas. It was designated a Recorded Texas Historic Landmark in 1936.
