Lange traveled the American West documenting the experiences of those devastated by the Great Depression. She wanted to use the power of the image to effect political change, but even she could hardly have expected the effect that a simple portrait of a worn-looking woman and her children would have on history. This image, taken at a migrant workers' camp in Nipomo, California, would eventually come to be seen as the very symbol of the Depression. The photograph helped reveal the true cost of the disaster on human lives and shocked the U.S. government into providing relief for the millions of other families devastated by the Depression.
