Auger holes are typically 2 to 4" inches across and do little or no damage to archeological deposits.

Back to Top The most common method of making chipped-stone projectile points, knives, and many other kinds of tools is to systematically chip away pieces from the edge of a large piece of flint.

Using atlatl-thrown darts, Aztec warriors were able to penetrate the light Spanish armor worn by Spanish conquistadors under Cortez, killing many.

They are small because the arrow shafts to which they were affixed were thin and light, often made of cane.

In prehistoric times most arrow points were made of chipped stone, usually chert ("flint").

In contrast, in many other circumstances it is not clear whether two things found side-by-side were actually left behind at the same time.

Most archeological sites do not represent moments in time, but are instead accumulations of things that may have been discarded days, months, or even years apart.

Archeologists pay a lot of attention to floodplains because many sites are located on or within alluvium.

Back to Top The Antelope Creek phase or culture is believed to have developed from indigenous Plains Woodland groups who moved south from the Kansas area, perhaps because of drought.

Nonetheless, hunting and gathering remained an important part of their livelihood.

(Alibates exhibit) Back to Top Often mistakenly called "bird points," tiny arrow points no bigger than your thumbnail were perfectly capable of killing a person or even a buffalo when attached to an arrow shot by an accurate archer.

Back to Top During floods, especially flash floods, much of the sediment carried down a hillslope or mountain is deposited where the water slows down and fan-shaped deposits (like deltas) form.

Prehistoric farmers in the American Southwest often farmed alluvial fans because of the alluvial sediment and because such places tend to be wetter.

A smart archeologist critically evaluates artifact associations and looks for compelling evidence that things found together belong together.
