STS060-93-081 (3-11 Feb 1994)--- The Imperial Valley was documented using three films - color visible (seen here), the American infrared film (Kodak Aerochrome 2443), and the Russian panchromatic infrared film (SN-10). Results of this test still await detailed science analysis. However it does appear that good data was acquired of the region, and this data will be complemented by photography acquired by the Mir cosmonauts. In this frame, the U.S.-Mexico border goes from the upper left to the middle right. It is discernible as a vegetation line between Calexico, California and Mexicali, Mexico. The darker vegetation north of that line is due to different agricultural practices, heavier uses of fertilizers and pesticides, and lined (tiled) agricultural fields allowing subterraneean runoff of saline irrigation runoff. South of the line, the more polluted water draining out of the U.S. agricultural areas into the Mexican area has resulted in higher soil salinities and a consequent reduction in agricultural productivity. At the center of the frame, a large settling and desalinization plant has been built to attempt to purify, to some degree, the polluted irrigation waters draining south out of California. The All-American Canal, which brings in water from the Colorado River (off the frame, to the right), is located in the middle right hand portion of the frame. To the upper left is the normally dry Laguna Salada.
