Montague Island, Baja California
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.
