Mexico - June 2nd, 2009

In the center of this ASAR image of Baja California, Mexico, currents at the mouth of the Colorado River are visible  as it discharges around Montague Island and into the Sea of Cortes.

The terrain above is mostly occupied by the vast Gran Desierto de Altar, one of the major portions of the Sonoran Desert of Mexico. Its dunes compose the only active erg dune region in North America.

In contrast with the arid desert, some agricultural areas are also visible in the upper left corner.

Isla Montague and Sea of Cortes - December 9th, 2008

The terrain in Baja California, Mexico, is very diverse, ranging from the desert visible in dark grey (right), called the Desierto de Altar, to agricultural areas (top center), to mountains (left).

The Colorado River spills around Montague Island into the Sea of Cortes. The island appears dark grey in the center and becomes lighter around the edges; this is due to the floodplain sediments sculpted by the movement of the waves and tides.

This area, the end of the Colorado River delta estuary, also has large white salt flats, visible to the west of the island.

Greenish sediments flow forth from the Colorado River, around Montague Island, and into the Sea of Cortes, left of the image center. Upon opening the full image, more of the sea and the Baja California peninsula in Mexico can be observed.

Near the north shores of the sea is the Gran Desierto de Altar, part of the Sonoran Desert. The dark brown circular area amidst the tan dunes is the Pinacate Peaks (Sierra Pinacate), a volcanic group of volcanic peaks and cinder cones.

Following the river northwards, one comes to an irrigated area in this arid region – the Imperial Valley in southern California. Continuing northwards through the agricultural zone, one finds the Salton Sea, a saline lake. The largest such lake in California, it covers a surface area of approximately 376 sq mi (970 km2).

This image stretches from the southern half of the California Central Valley, USA, in the upper left quadrant, to El Vizcaíno Biosphere Reserve, in Baja California, Mexico, in the lower right quadrant. In between the two, the Colorado River spills tan sediments around Montague Island into the Sea of Cortes, also known as the Gulf of California.

Several mountain ranges can also be observed, including the Sierra Nevada Range, which bounds the California Central Valley to the east, the Tehachapi Mountains, south of the valley.

East of the Sierra Nevada ranges lies the large desert of the Intermontane Plateaus a large, arid desert. The southern portion of this region, known as the Great Basin, contains salt flats, drainage basins, and many smaller mountain ranges running north to south.

The Colorado River pours thick tan sediments around Montague Island and into the Sea of Cortes. The sediments gradually take on a greenish appearance as they diffuse southward.

North of the rivermouth is the Gran Desierto de Altar, part of the Sonoran Desert. The desert’s vast sand dune field appears mostly tan here, with the exception of a dark brown circular area in the upper right quadrant.

This part of the desert is the location of the Pinacate Peaks, a group of volcanic peaks and cinder cones. The tallest of the peaks is Cerro del Pinacate (also called Volcan Santa Clara), elevation 3,904 feet (1,190 m).
