Alkali Ridge, also known as Alkali Point, is a set of widely scattered archaeological remains of the earliest forms of Puebloan architecture, representing a period of transition from scattered, pit-style dwellings to a settled agricultural lifestyle. These multi-story buildings and kivas have yielded high-quality ceramics, and form the type location for the Pueblo II period (c. 900 CE – c. 1100 CE).

It was declared a National Historic Landmark in 1964.[2]

Cacao residue was detected in Site 13 ceramics after testing by University of Pennsylvania and Bristol-Meyers Squibb researchers.[3]
