Colby Fluted
AKA: Colby Clovis
Cluster: Clovis Cluster
Description of Physical Characteristics and Flaking Pattern:
This is a medium to large lanceolate point with a flattened cross section.  The blade is excurvate with parallel sides.  The base ranges from deeply concave to a deep basal notch.  The face on both sides are fluted.  The flute primarily extends one third to one half of the blade from the base.  This point has a parallel to horizontal transverse flaking pattern. 
Size Measurements:

Total Length - 60 to 150 mm,  Blade Width - 28 to 46 mm (may have same measurements as Clovis type).

Additional Comments:

There is great debate over the classification of Clovis style points. It is argued that the same characteristics of any single type can be seen through-out the distribution of the Clovis type and represent normal variations of the Clovis point. Others argue that specific areas specialized the type and are seen with greater frequency in those areas. Therefore, these represent later variants and unique subtypes to the Clovis point.

This point is primarily found in northern Utah and into western Wyoming and southeastern Idaho.
