Broken Mammoth

The Broken Mammoth Archaeological Project began in 1990 following the discovery of the Broken Mammoth site in 1989.

Castle Hill Archaeology Project

With its commanding view of Sitka Sound, Castle Hill has long been a defining landmark of the local landscape. This rocky sixty-foot-high promontory was once the colonial capitol of Russian-America and the location of events which shaped U.S. history. Here, during the summers of 1995, 1997, and 1998, archaeologists from the State of Alaska, assisted by students and volunteers, scientifically excavated early nineteenth century deposits to recover artifacts and information.


The Kad'yak was a Russian three-masted wooden bark that sank off Spruce Island (Kodiak Archipelago) in 1860. The investigation of the wreck site in 2004 represents the first substantive underwater archaeology project to be conducted in the State of Alaska.

Tangle Lakes Archaeological District Special Use Area

The Tangle Lakes Archaeological District (TLAD) is 226,660 acres in size and encompasses land to the north and the south of the Denali Highway between MP 15 and MP 32. The TLAD is unique because it is jointly managed by two distinct agencies. The land to the north of the Denali Highway is managed by the State of Alaska, Department of Natural Resources (DNR), Division of Mining, Land & Water (DMLW), Southcentral Regional Office (SCRO) and the land to the south of the Denali Highway is managed by the Bureau of Land Management (BLM).
