This trip will include the Kirk Bryan Field Trip in the morning and conclude with the Geoarchaeology Field Trip in the afternoon. The San Marcos Springs in Hay County, Texas are part of a significant landscape for geological, hydrological, and archaeological interests. The artesian springs are among the largest in Texas and provide an exceptional opportunity for GSA attendees to study aquifer dynamics, karst geomorphology, and human history. This field trip proposes to lead attendees on a glass bottom boat tour, hiking tour of the fault zones of the escarpment, and tour of the cultural materials recovered over the years at the archaeological site. This trip is partially funded by the Geoarchaeology Division and the Kansas Geological Survey. The cost includes transportation (bus), boat fees, lunch, snacks, and water.
