The Jay Phase (7500-6800 BP)

updated December 18, 1999

This is the basalt Jay point the reader just clicked on to move to this page. It is almost whole, missing only its tip. The proximal and lateral edges of the stem have been ground. The maximum thickness is 7.0 mm. It has been resharpened into the shoulders and the extent of this resharpening is indicated by the white lines1. The point is not beveled.

Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 9.3 mm.
Resharpened with slight left-hand bevel.

As indicated by the white lines, the left edge in the left image (right edge in right image) has been resharpened almost to the proximal edge.


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

The resharpening on the left edge in the left image has cut into the left shoulder more than the right, creating an asymmetrical point. This could have happened in the previously displayed point, but the knapper chose to maintain the point symmetry. Sometimes, one shoulder is completely obliterated by resharpening; thereby, creating a single shoulder point that is often mistaken for a "Sandia" point.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.4 mm.
Resharpened with left-hand bevel.

The first impression is that this point is only a base (proximal fragment). However, it is pointed and was used in this condition.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.1 mm.
Resharpened with no bevel.

This point was used in this condition.


Fragment condition - proximal fragment.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.7 mm.
Resharpened with left-hand bevel.

The white on the face in the right image is a calcium carbonate (caliche) deposit.


Fragment condition - whole except a bit of the tip missing.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.3 mm.
Resharpened with left-hand bevel.

This is an example of the shoulders being removed by resharpening.


Fragment condition - whole.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 7.9 mm.
Resharpened with no bevel.

This is another example of the shoulders being removed by resharpening.


Fragment condition - proximal fragment.
Material - basalt.
Grinding - lateral and proximal edges.
Maximum thickness - 8.6 mm.
Resharpened, beveling is unknown.

This is the longest stemmed Jay in the Baker collection. Notice that only the right edge in the left image has evidence of resharpening. The other edge has not been touched with resharpening.


Fragment condition - whole.
Material - silty quartzite.
Grinding - lateral and proximal edges.
Maximum thickness - 9.3 mm.
Resharpened with no beveled.

This is the largest Jay in the Baker Collection.

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 has cut into the lateral edge grinding.

2 I have maintained the same size ratio of my images throughout all my WEB pages. The size of the Folsom, Belen, and Jay points are all the same relative size on your screen. If your computer system is set for a resolution of 800X600 or less, then some of these Jay points will be larger than the screen. You will have to scroll the images to see the entire point. I apologize for this, but unfortunately, I did not anticipate this problem when I first started making these WEB pages.
