XFP-132 Obsidian Knife, Sanak Island, Alaska

Bifacial knife, obsidian, Sanak Island, Alaska. CAT# XFP-132-4 XFP-132 is a lithic scatter in the south side of the dunes, on the south side of Sanak Island, Alaska. There are no other features at this location, which is typical of an eroding dune system. The artifacts are similar to those found in sites dating 400 BCE to 500 CE. These artifacts were scanned with either a Faro Edge Arm or a Minolta Vivid 9i. Processed in Geomagic or Polyworks. 4-8 photos were used for texture in ZBrush. The Sanak Island artifacts are presented as a result of the research conducted under grants NSF 0326584, NSF 0508101, NSF 1139266, NSF 1321411. H. Maschner, Principal Investigator. Original digitizing work done at the IVL at Id. St. Univ. Subsequent processing completed at Global Digital Heritage.
