Mexico: Sierra Madre Oriental
Mexico’s chief mountain system consists of the Sierra Madre Oriental, the Sierra Madre Occidental, and the Sierra Madre del Sur—all named with a variation of Sierra Madre, a Spanish phrase meaning Mother Highlands. The rugged Sierra Madres extend from northwest to southeast through Mexico and have deep, steep-sided barrancas (canyons). Landsat 7 acquired this image in 1999, and it depicts a desolate area of the Sierra Madre Oriental range on the border between the Mexican states of Coahuila and Nuevo León.
