Did you know that the Apollo astronauts studied geology in Big Bend National Park while training for the moon landings? Celebrate the 50th anniversary of the Apollo landings with this poster by artist and astrophysicist Tyler Nordgren. 12" x 18"
"[T]he astronauts were brought along in two separate groups... through the field areas on April 2-3, and April 15-16, 1964. The trip continued the basic geology study by requiring interpretation and mapping of well-exposed structural and stratigraphic relationships. Also included was an introduction to volcanic rocks along the Rio Grande River west of Big Bend National Park... On the first day they mapped two folded and faulted structures on aerial photos. On the second day there were four stops, two at road cuts of layered volcanic lavas and ash flows, a third at Bee Mountain to study an igneous intrusion, and a fourth at Santa Elena Canyon to study a large fault scarp."
