Which of the following is considered an archaeological feature?

The identification of nonmoveable structures and layers as an archaeological feature is significant because features are essentially the remains of human activity that cannot be easily removed from their context. These include structures such as buildings, walls, hearths, and other spatial organization artifacts created by past societies. They provide critical information regarding the lifestyle, architecture, and social organization of a particular culture.

Structures and layers help convey how people interacted with their environment and provide insights into the chronological sequence of occupation at a site. They are often studied through stratigraphy, which examines the layers of soil and material deposited over time, revealing how cultures changed or evolved. This contrasts with portable artifacts, organic materials, or trade goods, which, while important for understanding culture and economy, are not classified as features since they can be moved and may not provide the same context regarding spatial relationships and human constructions as nonmoveable structures do.
