Chaluka Site, Archaeological site in Nikolski, Alaska, US.

The Chaluka Site is a prehistoric midden mound in Nikolski on Umnak Island, about 210 m long, 61 m wide and 6.4 m deep. Excavations since 1938 have yielded over 4,000 artifacts, including ivory, bone and stone projectile points, stone lamps, Dorset-type stone knives and carved ivory deity figures.

Excavations at the site began in 1938 under the Smithsonian Institution and revealed human presence dating back to around 1,800 BCE. This long occupation makes the location important for understanding early Aleut history.

The site contains tools and weapons made from ivory, bone, and stone that show the skill of early Aleut craftspeople. These objects reveal how inhabitants adapted to island life and used the resources around them.

The location is remote and requires special permits for visits and research work. Specific details about access are kept confidential to protect the site from unauthorized disturbance.

The midden also held stone knives of a type otherwise known from Dorset culture sites in the Canadian Arctic, and carved ivory deity images. Excavations produced more than 4,000 artifacts, among them projectile points of ivory, bone and stone.
