The Birnirk Site is best described as a historic and archaeological site where some traces of the early Birnirk and Thule cultures were found. According to the remains and artifacts found in the area, the two ancient groups have settled in this location, near Barrow, Alaska for quite some time.

The Birnirk Site is composed of sixteen pre-historic mounds. They are arranged in rows that are almost parallel to the beach, which makes sense because it was once the settlement of two Northern Maritime cultures.

The Birnirk Site is currently maintained by the Ukpeagvik Inupiat Corporation under the supervision of the Bureau of Land Management. It was declared as a National Historic Landmark in 1962, and was listed on the National Register of Historic Places in 1966.
