Two Gunther Serrated Style <strong>Arrowhead</strong>s Made Of Transparent<br />

Obsidian. How Can You Know Which <strong>On</strong>e Is Ancient Or New?<br />

<strong>The</strong>se two obsidian points are<br />

magnified about 7 times their<br />

actual size, so that we can look<br />

closely at a few details which can<br />

help us note their relative age and<br />

authenticity.<br />

Again, the first thing which we<br />

can observe is the surface of the<br />

stone from which each point is<br />

knapped. <strong>The</strong> transparent<br />

obsidian point on the left has a<br />

fresh surface in all visible<br />

locations. <strong>The</strong> edges and corners<br />

are sharp, crisp, clean and<br />

undamaged. <strong>The</strong> points of the<br />

serrations remain pointed in<br />

appearance, even at this<br />

magnification.<br />

A couple of hinge flakes<br />

remain at the end of the<br />

pressure flake scars. <strong>The</strong>se are<br />

transparent, thin pieces hanging<br />

on still; they appear almost<br />

white in contrast to the<br />

clear or streaked material<br />

around them.<br />

<strong>The</strong> corner at the end of the<br />

base tang is still very<br />

squared away and freshly<br />

angled, with no weathering.<br />

This point is made from<br />

“Midnight Lace”<br />

obsidian from Glass<br />

Buttes in eastern Oregon.<br />

It was made by the author<br />

in early 2009 as part of<br />

a study on the<br />

knapping of the<br />

Gunther style of<br />

arrowheads.<br />

<strong>The</strong> surface of the gray,<br />

translucent obsidian arrowhead<br />

on the right reflects light, but it<br />

has a duller finish. This is the<br />

effect of the “hydration rind”<br />

formation which occurs on the<br />

outer surface of obsidian, from<br />

exposure to water over a long<br />

period of time.<br />

<strong>The</strong> intersecting edges along the<br />

sides of the flake scars, where the<br />

pressure flaking removals overlap,<br />

have a rounder, not so sharp look.<br />

<strong>The</strong> points of the serrations all<br />

look rounded at this enlargement,<br />

rather than sharp like on the<br />

other point.<br />

Plus, the corners of the base<br />

tang appear more rounded<br />

and smooth; this could be<br />

due to the design, though it<br />

can also be due to exposure<br />

and corrosion, similar<br />

to the rounding and<br />

smoothing effect visible<br />

on the serrations.<br />

This Gunther point<br />

was found in the<br />

1950’s in Shasta<br />

County of northern<br />

California, by<br />

Frank Estes, and<br />

is no. RR 303 from<br />
