The Sierra Madera crater is a complex impact crater (astrobleme) in southwestern Pecos County, Texas, United States. Strongly folded and faulted carbonate and siliciclastic rock layers from the upper Paleozoic to Cretaceous comprise the central structure, The impact site, at the southern edge of the Val Verde Basin, may have been underwater at the time of impact.
In the 1960s, the Sierra Madera crater was the subject of various studies conducted by the Astrogeology Research Program at USGS as part of the Apollo program, providing an analogous setting to lunar craters. Apollo 17's Gene Cernan and Jack Schmitt did some of their geological training here in March 1972.
