This trip provides a great opportunity to bridge terrestrial and extraterrestrial geology through the lens of impact sites. We will visit two confirmed impact craters of drastically different size and style: the ~8-mile diameter Sierra Madera structure near Fort Stockton and the Odessa crater and meteorite field in Ector County. It also will visit two proposed structures: Bee Bluff, south of Uvalde, and Hico, southwest of Fort Worth. We will discuss impact geology and terrestrial structures as planetary analogues. Cost includes transportation (full size SUVs), one night in Fort Stockton (double occupancy), lunch, snacks, and water.
