Discovered in 1970 during the construction of the Trans-Alaska Pipeline, it yielded a radiocarbon date of 10,540 B.P., making it the oldest site of human activity then known in the state at the time of its discovery.

[4] The Gallagher Flint Station site is located in the foothills on the north side of the Brooks Range in far northern Alaska, near the Sagavanirktok River.

There are three separate areas of archaeological interest within the site, two of which overlap slightly in their vertical stratigraphy.

Locality 1A yielded a radiocarbon date of about 650 BCE, and tool finds there included fragments of a drill bit made of green chert.

None of the three localities included any remains of animal-based tools (made with antler, bone, or other animal parts).
