Laguna Madre and Sierra Madre Oriental Range, USA and Mexico25.1N 98.7W
The Laguna Madre (meaning “Mother Lagoon” in Spanish), in the upper right corner, appears silvery in color due to sun glint. The lagoon is actually two long, shallow bays along the western coast of the Gulf of Mexico, in both the USA and Mexico. The two bays are separated by the mouth of the Rio Grande.
An area of green coastal plains can be observed to the west of the lagoon. Further west lies the Sierra Madre Oriental mountain range, whose peaks appear darker brown and more marked as one moves southward. Some areas of white and tan arid terrain can be seen further to the west and to the north.
