Anthropic epipedon
This soil in New York City formed in human-transported material with human artifacts in the profile, such as brick, glass, and metal. The surface layer is an anthropic epipedon. The anthropic epipedon is a thick horizon that formed in human-altered or human-transported material. The key feature is that it formed as the result of intentional human alteration (but not simply by the common agricultural practices of plowing and amending the soil with fertilizers). Its landscape setting (such as a raised surface due to filling) and/or presence of human artifacts are key characteristics.
