Prehistoric Archaeology of the Fortymile River Drainage

Sam Coffman

In 2015, the Fairbanks District Office of the Bureau of Land Management and the University of Alaska Museum of the North jointly began surveying the main tributaries of the Fortymile River drainage that lies 290 km (180 mi) east of Fairbanks, Alaska. The goal of this multi-year project is to document prehistoric archaeological sites and build a cultural record for the area.

The main stem of the Fortymile River is 64 km (40 mi) long and is one of the larger tributaries of the upper Yukon River. Main tributaries include the North, South, and Middle forks, the Mosquito Fork, and the Dennison Fork. Altogether, the main tributaries of the Fortymile drainage measure 800 river kilometers (500 mi) and drain roughly 14,500 km² (3.6 million ac²) of Interior Alaska.

To date, this project has recorded 43 previously unknown archaeological sites and reinvestigated two known sites. Each of the sites recorded all have provided unique insight into understanding the human past of the area. Sites include small ephemeral lithic scatters, cache features, to substantial winter camps. New raw material sources have also been documented during this project. Research highlights of this project may be found in the following journal report:
