I found this on a valley top in the plains of canada. 120 miles north of Minot ND. Any confirmation on type and era would be appreciated. We generaly dont find anything this old.
Knife River Flint can have patina that looks almost to a blueish white. There are also some chalcedony materials in North Dakota that do the same. I assume it would be similar north of the boarder.
The only thing I question as far as being an Alberta point is the short stem. Generally the stems of Alberta points are longer than Scottsbluff points.
