The middle to the bottom one third of the blade is usually the widest point of the blade. The base is primarily straight, but may range to slightly convex, and never concave (see below). Heavy basal grinding is present on the hafting regions, but this point lacks any basal thinning.

The size of Agate Basin point can range from 63 mm to 128 mm in length. The typical width is less than 32 mm. Thickness averages 8 mm. The Agate Basin was named by Frank H. H. Roberts Jr. in 1943 for examples that were recovered from the Agate Basin site in eastern Wyoming.

Agate Basin are long lanceolate points which lack flutes. They are created from a large bifaces by reducing their size using percussion flaking, then shaping the sides using pressure flaking. This shape is postulated to have been good for reworking – especially in the case of breakage.

What is Agate Basin? The agate basin projectile point style is long and narrow or slender. It is sized medium to long. The edges are parallel or slightly convex. The portion of the blade that...

Paleo Indian and Early Archaic (10000-6000 B.C.) Agate Basin spear point or knife. Agate Basin points are found across a wide geographic region from Texas to northern Canada and from Colorado to New York.

The iconic Paleoindian projectile points of the northern portion of the North American Great Plains—Clovis, Folsom, Agate Basin, Plainview (Goshen), Hell Gap, Alberta, Scottsbluff, and Eden—span nearly 4,000 radiocarbon years.

Agate Basin This type is named after points found at the Agate Basin site complex in eastern Wyoming. Excavations at this well-stratified site produced multiple point types, including a Folsom–Agate Basin–Hell Gap sequence, each associated with discrete beds of …

Hell Gap contains projectile points from Llano tradition, Clovis and Folsom, and the Plano tradition, Agate Basin, Alberta, Frederick, Goshen (Plainview), Lusk, Hell Gap, Midland and Cody complexes. [6]

AGATE BASIN Description: a lanceolate point with a long and slender form, convex blade edges taper to the point and the base which is often straight; often displays parallel flaking and the basal edges are usually ground Size Range: 6.0 cm - 15.2 …

Other types that occur in the southern Rockies include components of the traditional Plains late Paleoindian sequence (e.g., Agate Basin, Hell Gap, Eden, and Scottsbluff) and its Great Basin counterpart (Great Basin Stemmed series).
