Salton Sea.
A sepia-toned historical photograph captures a wide, flat expanse under a pale sky. In the foreground, a figure wearing a wide-brimmed hat, long sleeves, and trousers with suspenders sits atop a heavy, dark-colored agricultural plow or scraping machine equipped with large, spoke-style wheels. The machine is positioned on the textured, light-colored ground. In the background, the horizon line is low and level, featuring a distant, dark line of what may be small hills, along with several tiny figures and equipment scattered across the horizon. Below the image, a faint, handwritten caption reads: "Plowing Salt at Salton. Indio." To the right of the main image, a vertical color calibration strip is visible, showing a sequence of colored squares including blue, green, red, yellow, and magenta, alongside a grayscale stepped scale.
