This summer is dedicated to fieldwork and laboratory examination. The surface could serve as a datum for investigation of the vertical magnitude of faulting in the Big Bend area. Collection of invertebrate fossils from the younger part of the Boquillas Formation.
Data collection is nearly complete.
There are a few areas where laboratory results suggest further field work. Two surfaces meeting the requirements have been identified. A second MS thesis is beginning, and substantial manuscript exists, though much work remains. 1998 Time-parallel topographic simple surfaces, Boquillas Formation, as established by invertebrate fossils.
