An oblique view of northeastern Mexico and the Rio Grande Valley of Texas, as photographed from the Skylab space station by one of the Skylab 4 crewmen. The camera used was a hand-held 70mm Hasselblad, with SO-368 medium-speed Ektachrome film. Mexico's Sierra Madre Oriental Mountains are in the center of the pictures. The Gulf of Mexico is in the background. Note the lakes on the Rio Grande River. Monterrey is near the center of the picture. Field patterns in the lower Rio Grande Valley can easily be identified. The stark, linear roughness of the Sierra Madre Oriental Mountains is the most prominent feature. The mountains are the subject of geological studies using space photography.
