Side-notched points (pl. 22, c, d, e).—A single example differs in some degree with specimens recovered last season. It is smaller, having a length of 3 cm. and with a slightly concave base. Though this is a surface specimen composed of obsidian, the surface has been so highly patinated that it bears little resemblance to its parent material (pl. 22, d).
Contracting-stem points (pl. 22, f, g, j, k).—This type has some latitude in respect to the shape of the stem and some refinement probably could be made. Some specimens have well-defined shoulders and are with stems which contract to a sharp point (pl. 22, g, k), being reminiscent of points associated with the Hunting and Canalino cultures of the Santa Barbara coast. In other instances shoulders are less well-defined, or the stems terminate in more rounded bases. The lengths range from 2.7 cm. to 4.2 cm. The materials include basalt, chert, chalcedony, and obsidian.
Lozenge points (pl. 22, h, i, l-u).—Numerically this group constitutes the largest class of the small projectile points. Were a larger series present, some refinement of types might be attempted. Of the fourteen specimens, some tend toward diamond shapes, whereas others border small leaf or stem forms. Lengths range from 2.5 cm. to 4.1 cm. Materials used are obsidian, basalt, chert, and quartz.
Large Blades and Large Points
The large blades and points collected this season show some variation over those of last year, both in finishing technique, form, and material. Frequently, for lack of established terminology, it is difficult to distinguish between what might be termed a chipped knife, leaf-shaped blade, or a coarsely made projectile point. We attempt only a rough breakdown between blades and large points, either of which if hafted could serve the purpose of a knife. All specimens are illustrated and may be judged by the observer.
Described below are only those additional specimens collected this year. For full details the 1950 report should be consulted.
Large blades (pl. 21, a-g).—
1. This specimen comes from a depth of 48 to 54 inches, marking the deepest level from which any blade was taken. Though it shows an old break, enough remains to offer a computed length. The form is leaf-shaped and probably pointed at both ends. Computed length, 9.2 cm.; width, 4.6 cm.; thickness, 1.2 cm. Material is basalt (pl. 21, b).
2. Basal half of what was probably a leaf-shaped blade. Incomplete length, 4.5 cm.; width, 5.4 cm.; and 1.4 cm. thick. Material is basalt (pl. 21, c).
3. Larger half of a basalt blade, showing some attempt to reshape the broken margin. Incomplete length, 7 cm.; width, 4.5 cm.; and 1.5 cm. thick (pl. 21, a).
