Mexico - May 1st, 2011

The Salton Sea, a large lake near the California-Mexico border, can be observed in the upper left quadrant of this image.

South of the sea is a large agricultural area that stretches towards the Sea of Cortez (Gulf of California). This green, field-covered area is interrupted by the grey of the city of Mexicali, the capital of the Mexican state of Baja California, situated on the U.S.-Mexico border adjacent to Calexico, California.

The Mexicali Valley is one of the largest and most fertile valleys in Mexico. The Valley has over fifty different crops and is similar to the Imperial Valley in its agricultural production. The Mexicali Valley is a primary source of water for the region, having the largest irrigation district in Mexico.

Continuing southeastward past the agricultural zones, one comes to the sandy Desierto de Altar and then to the Sea of Cortez. Sediments from the Colorado River spill into the northern end of the sea.

Mexico-USA Border and Algodones Dunes

Mexico-USA border - December 9th, 2008

Mexico-USA border - December 9th, 2008

The border between the Mexican state of Baja California and the state of California, USA, runs through the center of this radar (ASAR) image.

On the left, the city of Mexicali, Mexico, appears bright white. Just above is its sister city, Calexico, California. The border appears as a line, between the two cities, accentuated by the difference in organisation and color (intensity of grey) of the crops near them.

The line continuing eastward from the Mexicali area is actually not the border, but rather the US Highway 8 running just north of it.

On the Mexican side of the border, on the bottom left, part of the Sierra Madre Occidental mountain range can be seen in light grey and white.

On the USA side, the dark area is a patch of desert. The diagonal line through it is the Algodones Dunes, a large erg (sand dune field). It is approximately 72 kilometers long by 10 kilometers wide (45 miles by 6 miles) and extends along a northwest-southeast line that correlates to the prevailing northerly and westerly wind directions.
