A LITHIC CAST of an obsidian projectile point from the site of Rimrock Draw Rockshelter(35HA3855)  in Harney County, Eastern Oregon. This site is one of the most important in the Americas, with some of the oldest possible dates for human occupation going back as far as 18,300 years ago. It has been under excavation and study by the University of Oregon/Museum of Natural and Cultural History/Patrick O'Grady, and the Bureau of Land Management since 2011,  and has become one of the most scientifically important in North America, due to some of the oldest dates for human occupation in the continent. In 2012 the excavations found stone tools beneath the level of a Mount St. Helens eruption and layer of ash, dating 15,300to 15,600 years ago, and later found scraper tools and cultural debris below a layer with camel enamel dating 18,300 years ago.  This example here represents a type from after the Ice Age, from the Late Paleoindian to Early Archaic(around 7 to 11,000 years ago), and is related to the Western Stemmed Tradition/Parman types. It was originaly made in Oregon Obsidian with slight grey banding, believed to come from the Tank Creek source, and measures 11cm(4 and 3/8th inches) long, and 3cm wide. Its max width is 8mm, and is masterfully knapped. The authentic original was sent to Occpaleo in 2025 for molding and casting, by Burns Bureau of Land Management/Rimrock Draw Rockshelter Field school/Patrick O'Grady.
