Projectile point s, sometimes just called “points,” are sharp tools, such as the spearhead in this photograph. Most ancient projectile points were made of stone or bone. The large spearhead above was crafted from obsidian , a type of volcanic glass. Archaeologist s and anthropologist s sometimes classify a site or an entire culture by the shape of the projectile points found in the area. The presence of a particular style or type of point helps identify the time period in which it was made, and by what tradition or culture. Anthropologists have classified more than a hundred distinct points in North America. This spear point, for instance, has a stemmed shape, owing to the rounded stem at the bottom.

In recent months, a man was arrested twice for looting at Anderson Marsh State Historic Park here, where archaeological deposits date back 13, years or more. She supervises a legion of volunteers who look out for looters, supplementing surveillance cameras along key trails. For tribal members like Dino Beltran, treasurer of the Koi Nation of Northern California, the lands around Anderson Marsh are sacred, and the antiquities cloistered among the turtles and great blue herons are his legacy.

His great-great-grandfather and other family members were born on an island in the lake. The city of Clearlake, just over miles north of San Francisco, was named for its ancient lake, home to the indigenous Pomo people who settled here some 14, years ago. The tribes have weathered displacement, violence and intergenerational trauma.. The looting of Native American sites is particularly egregious given the history, said John Parker, an archaeologist who led efforts to save Anderson Marsh.

By Richard N. Everything today seems to be political, and we collectors are not immune to controversy and must revisit our place in history. Political correctness has taken over common sense in much of our lives, and we collectors have not been untouched. New laws have affected every facet of our finding, collecting, selling, or keeping our “treasures”.

Native American activists have sided with political parties who then have initiated new laws. A disinterested general public is unaware of all this and blindly soaks up government-fed news releases that collectors are evil. This has become quite evident to me as I tried to research this report. We, meaning private citizens, are not allowed access to archaeological records or reports for the sake of preventing looting and to not offend Native Americans.

I must first apply to a Native American group having influence over the geographical area of which I had interest stating what material was to be reviewed and what my purpose was. The Kee Mound was recorded to have as many as burials. Need I say more about my chances of getting Native American assistance to accessing records at University of California Berkeley? I am grateful to several California archaeologists for their cooperation at completing this report.

These artifacts help to explain much about the different people and cultures that once lived in what is today the Stockton area. When archaeologists study artifacts, they focus on what are called “diagnostic” objects. For instance, a stone tool that is fashioned a certain way can be dated to a particular time period based on its style and shape. The same is true for pottery, glass bottles, and even fishhooks. An artifact that is in good condition barely broken, if at all with a distinctive craftsmanship is considered to be diagnostic.

Considered one of the finest ever found in the state, the axe has been featured in several archaeological publications. Reminders of North Carolina’s earliest inhabitants appear in the form of Indian arrowheads that were once plentiful in central North Carolina. These Carolina gems have been found in almost every area of North Carolina, especially in the central Piedmont region.

There are numerous collectors throughout that area who have hunted, traded, bought and otherwise accumulated collections of various sizes over the past decades. The earliest inhabitants of what is now North Carolina were the Paleo Indians of the Clovis Culture, who made beautifully flaked stone Clovis points read about a North Carolina museum highlighting Native American culture.

Fluted channels on the points aided in “hafting” or attaching them to a spear shaft. Clovis points date back 10, to 12, years ago and are infrequently found at various locations throughout North Carolina as well as other areas the United States. Clovis points are highly prized by collectors and are displayed with pride, considering their rarity. Later cultures, like the Hardaway people, inhabited various areas of the Piedmont region in slightly greater numbers than did the Clovis.

Archaeologists exploring the remote reaches of a military training base in southern California have uncovered nearly 9, artifacts that represent more than 11, years of human history in the Mojave Desert, a new study reports. The evidence turned up by this research led archaeologists to propose that two sites on the base be placed on the National Register of Historic Places. Among the finds was the lone biface blade, discovered near the surface in a northern stretch of the range.

This biface blade, fashioned in the Clovis style from local jasper, was found near the surface on the Marine Corps Air Ground Combat Center, and is thought by archaeologists to be around 13, years old. Elsewhere on the base, the review of previously unpublished research showed that dozens of other distinctive stone points had also been uncovered, dating back as much as 9, years. Near a dry lakebed, or playa, by the western border of the base, for example, archaeologists in found at least 19 points fashioned in the Western Stemmed Tradition at various sites in the area, as well as more than 14 so-called Pinto points, whose triangular style has been found around the Great Basin at sites dating back 6, to 8, years.

Arrowheads are among the most easily recognized type of artifact found in the world. Untold generations of children poking around in parks or farm fields or creek beds have discovered these rocks that have clearly been shaped by humans into pointed working tools. Our fascination with them as children is probably why there are so many myths about them, and almost certainly why those children sometimes grow up and study them.

Here are some common misconceptions about arrowheads, and some things that archaeologists have learned about these ubiquitous objects. Arrowheads, objects fixed to the end of a shaft and shot with a bow, are only a fairly small subset of what archaeologists call projectile points. A projectile point is a broad category of triangularly pointed tools made of stone, shell, metal, or glass and used throughout prehistory and the world over to hunt game and practice warfare.

A projectile point has a pointed end and some kind of worked element called the haft, which enabled attaching the point to a wood or ivory shaft. There are three broad categories of point-assisted hunting tools, including spear, dart or atlatl , and bow and arrow. Each hunting type requires a pointed tip that meets a specific physical shape, thickness, and weight; arrowheads are the very smallest of the point types.

In addition, microscopic research into edge damage called ‘use-wear analysis’ has shown that some of the stone tools that look like projectile points may have been hafted cutting tools, rather than for propelling into animals. In some cultures and time periods, special projectile points were clearly not created for a working use at all. These can be elaborately worked stone objects such as the so-called eccentrics or created for placement in a burial or other ritual context.

That “tink, tinkle” means a window has opened to reveal the lives of people who lived as long as 9, years ago. Their work has given insight into how prehistoric Native American hunter-gatherers used the lake, providing evidence about whether they hunted bears, used boats or fished.

Before they disappear, park officials want to record them and come up with strategies for which sites they should try to protect, if they can. Last year, two graduate students and an undergraduate worked with him, and in there were 10 graduate students on the payroll. Many scientific theses have resulted from the work. MacDonald says their initial research involved completing the archaeological survey of the lake, including 25 never-examined miles on the eastern shore.

Receding Waters in California Expose Artifacts to Plundering

The hunting and gathering peoples who populated the South Texas Plains throughout prehistory left no ruins like those of the settled farmers of Mexico or the American Southwest. Most of what remains are artifacts made of stone, shell, pottery, and sometimes bone, that have survived the ravages of time. Archeological evidence, however, clearly shows that trade and exchange were very important to the native peoples of south Texas, beginning in Paleoindian times, and, as the above quote from Cabeza de Vaca demonstrates, well into the Historic era.

Such objects must have had an importance that went beyond the daily grind of food-collecting. They also needed inland cane suitable for arrow shafts and perhaps preferred bow-making wood. The Cabeza de Vaca account shows trade processes in place which may date back thousands of years.

YANCEYVILLE, N.C. (AP) — Gordon Godwin loves arrowheads. Carbon dating shows the points are about 10, to 15, years old, jasper or obsidian giving them a rippled look and very sharp, almost serrated, edges.

Obsidian outcrops all over the world, and was preferentially used by stone tool makers because it is very easy to work with, it is very sharp when broken, and it comes in a variety of vivid colors, black, orange, red, green and clear. Obsidian contains water trapped in it during its formation. That new rind is visible and can be measured under high-power magnification 40—80x. By measuring the thickness one can easily determine if a particular artifact is older than another relative age.

If the rate at which water diffuses into the glass for that particular chunk of obsidian is known that’s the tricky part , you can use OHD to determine the absolute age of objects. It’s nearly a sure bet that everybody who ever made stone tools and knew about obsidian and where to find it, used it: as a glass, it breaks in predictable ways and creates supremely sharp edges. Making stone tools out of raw obsidian breaks the rind and starts the obsidian clock counting. The measurement of rind growth since the break can be done with a piece of equipment that probably already exists in most laboratories.

It does sound perfect doesn’t it? The problem is, the constant that sneaky D up there has to combine at least three other factors that are known to affect the rate of rind growth: temperature, water vapor pressure, and glass chemistry. The local temperature fluctuates daily, seasonally and over longer time scales in every region on the planet. Archaeologists recognize this and started creating an Effective Hydration Temperature EHT model to track and account for the effects of temperature on hydration, as a function of annual mean temperature, annual temperature range and diurnal temperature range.

Obsidian , igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica about 65 to 80 percent , is low in water , and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass. Though obsidian is typically jet-black in colour, the presence of hematite iron oxide produces red and brown varieties, and the inclusion of tiny gas bubbles may create a golden sheen.
