Elko Series
Elko series points consist of large, corner-notched triangular forms with variable shoulder and haft treatment. This series has been divided into three types: Elko Corner-notched, Elko Eared, and Elko Contracting-stem (Heizer and Baumhoff 1961:128). A side-notched variety was defined, but has not been accorded temporal or spatial significance (cf. Heizer et al. 1968; Holmer 1978:35; Thomas 1981:21). Thomas (1981:22) proposes moving the Elko Contracting Stem variant into his Gatecliff Series; Holmer (1978:35) suggests that they are best considered Gypsum type variants. O'Connell (1967) demonstrates the utility of Elko Corner-notched and Eared variants as temporal markers, and these are the two predominant Elko variants.

Elko Corner-notched:

Elko Corner-notched points are triangular blade forms with straight to slightly convex edges, and corner notches that form tangs or downward sloping shoulders and expanding stems (Holmer 1978:35).

Type Site: Wagon Jack Sheller (Heizer and Baumhoff 1961).

Temporal Distribution: C. 4500-1500 B. P.; Middle-Late Archaic.

Elko Eared:

Elko Eared points are triangular blade forms with straight to convex edges, expanding stems, and markedly concave basal margins or notches.

Type Site: Wagon Jack Shelter (Heizer and Baumhoff 1961).

Temporal Distribution: c. 4500-1500 B.P.; Middle-Late Archaic.
