During the Great Migration, a young Delores Martin and her family moved in 1945 from Pine Bluff, Arkansas, to Sioux City, Iowa. Like many of Sioux City’s Black residents, they landed in a redlined neighborhood, home to meatpacking plants and acres of stockyards, where hogs and cattle were corralled, sold, and slaughtered. The stench of blood and manure hung in the air, clung to their nostrils, and filled their lungs, along with coal ash from the railroads that spliced the neighborhood.
