Rock suspected of being a Stone Age curated manuport may have been worked to enhance perceived facial features in the random surface pattern

Collector Dennis Boggs recognizes certain stone material as "exotic" to his locale and in unnatural concentrations and flags it for closer inspection for evidence of human modification.

Dennis Boggs obsidian tool, Columbia River valley. Mode I Oldowan tool forms like this are plentiful but not accounted for by American archaeologists.

Obsidian hydration dating on this fracture might be possible.

Dennis Boggs find, Columbia River valley, Irrigon, Oregon. Levallois point, American style. I have identified Middle-Paleolithic portable rock art motifs in Dennis' collection. Most of the tools found near or with the art are cutters, choppers, scrapers and pounders. A point like this is rare.

  1. I am in the Springfield area in Oregon and found something extremely similar to the tools shown here. What other resource may I find out information pertaining to these types of artifacts and their dating. The hydration dating process seems to be the route to go but who does one call to have this done.
