In 2006, Jim Olson, owner of the Holguin Ranch in Presidio County, graciously provided funding for the formal recording of previously located sites on his ranch, the evaluation and submittal of sites potentially eligible for the Texas Historical Commission's State Archeological Landmarks (SAL). A total of 14 sites were formally recorded and 12 were nominated and determined eligible as State Archeological Landmarks. These sites consisted of prehistoric open campsites, rockshelters and caves, prehistoric special use sites, and historic structures, many of which were affiliated with the Cielo complex. The Historic Lands Plaque was awarded to Jim Olson for his devotion to protect and preserve our cultural resources here in the Big Bend. Jim had worked with the Center for Big Bend Studies in conjunction with the Texas Historical Commission to protect important sites on the Holguin Ranch. Jim will be sorely missed.
