Fredrick Lanceolate
Cluster: Plano Lanceolate Cluster Description of Physical Characteristics and Flaking Pattern:
This is a thin medium triangular lanceolate point with a thin elliptical to flattened cross section. The blade is slightly excurvate. The widest part this blade is usually above the base. The base varies from straight to slightly concave. Grinding on the hafting area is commonly seen. This point has a parallel to oblique flaking pattern.
Size Measurements:
Total Length - 60 to 80 mm, Blade Width - 20 to 30 mm, Basal Concavity 0 to 3 mm
Total Length - 60 to 80 mm, Blade Width - 20 to 30 mm, Basal Concavity 0 to 3 mm

Additional Comments:
These points are similar to James Allen points but differs in that the base of this point is straight to slightly concave while the base of the James Allen point is deeply concave.
Frison (1991) states that this type “is an abrupt change from stemmed points with transverse pressure flaking” to lanceolate forms with parallel oblique flaking . He further notes that Jimmy Allen points from the type site in Wyoming are very similar to Frederick points except that the Jimmy Allen point is lanceolate with a deep basal concavity.

Distribution Comments:
This point is primarily found in the western Plains and into the Rocky Mountains. They seem to be associated with higher altitudes in these regions. This points are also found into the southern Plains region and into northeastern New Mexico.
