S74-23654 (22 June 1973) --- This mosaic of Baja and the Sea of Cortez in Mexico (28.0N, 112.0W) is a composite of six 70mm photos carefully pieced together to appear as one. Mosaics such as this one are useful to portray a large area in a single format instead of many photos covering only partial images. In this mosaic, almost the entire area of the Sea of Cortez, the adjacent Baja Peninsula and part of the Sonoran Desert of northwest Mexico can be seen. Photo credit: NASA
