- The Bajada Phase

The Bajada Phase (7500-6800 BP)

This is the quartzite Bajada point the reader just clicked on to move to this page. It is whole, but resharpened with the extent of the resharpening indicated by the white lines1. Originally, it was probably twice as long as now. The proximal and lateral edges of the stem have been ground. The maximum thickness is 7.9 mm. The point has a slight left-hand beveled. Click on the image to see a larger view.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 9.7 mm.
Resharpened with no bevel.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 9.8 mm.
Resharpened with no bevel.

The tip of this point was broken off which gives it the appearance of missing. The broken edge was subsequently thinned to resharpen the point and this is the reason I call it whole.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 9.0 mm.
Resharpened with no bevel.


Fragment condition - missing left part of base (left image).
Material - Edwards2.
Grinding - lateral and proximal edges.
Maximum thickness - 11.4 mm.
Resharpened with slight left-hand bevel.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.6 mm.
Resharpened with no bevel.


Fragment condition - proximal fragment.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.8 mm.
Resharpened with no bevel.


Fragment condition - whole.
Material - jasper.
Grinding - lateral and proximal edges.
Maximum thickness - 7.6 mm.
Resharpened with right-hand bevel.


Fragment condition - whole.
Material - opaque obsidian.
Grinding - lateral and proximal edges.
Maximum thickness - 7.8 mm.
Resharpened with right-hand bevel.

I included this point to demonstrate the extent the Bajadas were often resharpened. This projectile is whole.

Notes

1 The reader should not interpret the white lines in these images as the end of the lateral edge grinding. They represent the end of the resharpening, which began at the distal end. In most cases, they will be one of the same because the resharpening often cuts into the lateral edge grinding.

2 Edwards chert is from central Texas so the material in this point is a long way from home. The Archaic folks are not know for importing material over long distances, plus, I am unaware of any Bajadas found in Texas. So how did this Edwards Bajada find its way into the Central Rio Grande Valley?

The Archaic didn't import exotic materials, but the Paleoindians did. It turns out that there is a Paleoindian site (Belen) located 500 feet for the site where this point was found. And, yes there is Edwards in this site. Four paleo-end-scrapers, a biface fragment and numerous chips of Edwards were found in the Belen site. Plus several of the pieces retain the cortex. So I suggest an opportunist Bajada knapper walked through the Paleoindian site and found a large Edwards chunk and used it.
