Tiger Chert (NW Colorado / SW Wyoming)
Tiger Chert
Tiger Chert, is one of my favorite lithics, a northwest Colorado / southwest Wyoming material.
I have seen very few points made from this lithic, It may be from the small quarry with a small distribution of the lithic. It could be the nature of the material its self with the bands rendered it weak along the bands. I have seen more in tools such as scrapers more predominate. This lithic has a long history of use, dating back to Clovis (Paleo era artifacts)found at the Mahaffy Cache in Boulder Colorado.
Here is a link, note the pic on the forefront of the Tiger chert blade. Rare Clovis artifacts document Boulder's prehistory - Boulder Daily Camera:
Many of the natural tabs are thin and flat. Some of the Zebra Flint has very obvious bands before it is knapped. After a blade or point is knapped some flintknappers have placed the blade in direct sunlight for one or two months to bring out the bands. I have included six pictures showing obvious bands and six pictures that don't show the bands. This lithic material is known by many names including; Oil Chert, Tiger Chert, Bridger Basin Chert and Green River Chert.
Here are a few artifacts and lithics, personal finds.
