Discovery and Investigation

In the summer of 2007, NPS archaeologists discovered bone and stone artifacts eroding out of a lake side bluff near the Noatak river. Over the course of the next two summers intensive investigations at the site would expose a frozen and stratified deposit preserving the remains of a 4000 year old Denbigh Flint Complex Paleo-Eskimo camp.

AMR-186, as the site is officially known, is the only Denbigh Flint Complex site with such excellent organic preservation ever discovered. In addition to the thousands of faunal remains and stone tools, hitherto unknown engraved bone artifacts were discovered, representing the only such artifacts ever found in a Denbigh site.

The following images were selected to present some of the aspects of the fieldwork activities involved in the discovery and investigation of the site.
