Archaeological Culture: Paleoindian, Cody Complex

Geographical Range: The Great Plains from southern Canada to New Mexico; few Southwest and Great Basin locations, including isolated points in Arizona, a camp in the Black Rock Desert, Nevada, and to the north, sites along the Snake River Plain corridor.

Date Range: 10,000 – 8000 B.P. (Muniz 2005).

Size:  Average: 60 mm long, 19.4 mm wide, and 6.1 mm thick; stem length: 15.3; stem width: 17.6 (Dello-Russo et al. n.d.: Table 1); Range: 71-155 mm long, 13-19 mm wide (Justice 1995:243).

Shape: Narrow-stemmed lanceolate, with parallel lateral margins, small square shoulders, pronounced median ridge, and near perfect symmetry; stem is straight and square.

Cross-section: Diamond-shaped.

Base: Straight; occasionally eared.

Flaking: Serial pressure; well-controlled and designed to create the median ridge on the point. Flake removals are symmetrical, with each flake removed from a side matched by one removed from the opposite edge.

May be present on the lateral margins of the stem to the shoulder.

Materials: Chert, chalcedony, porcellanite, quartzite, silicified wood.

Other Names: Eden Valley Yuma, Eden Eared, Hixton, Cody. Muniz (2005) and others include Albert points as early variants of the Cody Complex, which includes Eden and Scottsbluff points.

Comparisons: Scottsbluff points are less well-made, with soft-hammer percussion scars and slightly expanding stems. Other Paleoindian lanceolate points typically lack square shoulders and stems.
