Vance Haynes and a Team of Arizona Archaeologists Determine Evidence for Clovis Era Comet Impact Flawed

A team of researchers from the University of Arizona has revisited evidence pointing to a cataclysmic event thought by many scientists to have wiped out the North American megafauna – such as mammoths, saber tooth cats, giant ground sloths and Dire wolves – along with the Clovis hunter-gatherer culture some 13,000 years ago. The team obtained their findings following an unusual, multidisciplinary approach and published them in the Proceedings of the National Academy of Science (PNAS).

Younger Dryas Comet Impact Hypothesis - Astronomer Proposes Multiple Impacts from Portions of a Known Comet

A British astronomer has published new evidence that North America was strafed by thousands of fragments from a massive comet about 12,900 years ago, a theory he says is the best explanation yet for why the planet was plunged into a 1,000-year cooling period and dozens of Ice Age mammals went extinct at that time.

Why Does the Younger Dryas Matter?
What caused the last great stab of cold 13,000 years ago? Almost overnight, it seems, something drove the gradually warming Northern Hemisphere back into the ice age for 1,000 years or more until warming resumed. People researching the behavior of ancient climate have been ruminating over this question for 20 years now, ever since they detected unexpectedly sharp changes in temperatures in a variety of sources -- ice cores, ocean sediments, pollen layers in old dirt.

Dawn of the Anthropocene Epoch? Earth Has Entered New Age of Geological Time, Experts Say

Geologists from the University of Leicester are among four scientists- including a Nobel prize-winner -- who suggest that Earth has entered a new age of geological time. The Age of Aquarius? Not quite -- It's the Anthropocene Epoch, say the scientists writing in the journal Environmental Science & Technology. And they add that the dawning of this new epoch may include the sixth largest mass extinction in Earth's history.

Is Enforcement of Section 106 a "Government Taking?"

In the lawsuit, filed in Federal District Court in Providence in August, Downing claimed the measures the state had taken to prevent it from developing the subdivision had amounted to a “de facto” taking of the property. The state is seeking to create a public archaeology park out of private land that Downing had already started to develop, not only violating the developer’s private property rights but also causing it considerable financial harm, the lawsuit states.

Native America, Archaeology, and Development

Legally, Native Americans have a growing role in shaping the cultural preservation process. They have an unofficial role too: giving voice to our ambivalence about "progress."

Monthly Presentations Help Preserve Navajo Culture

The staff at the Navajo Nation Museum is on a mission to preserve Navajo language and culture. Part of the effort includes monthly cultural presentations that have now been going on for more than a year. For many of the participants, the information from the presentations is something they had once known. “It’s good. It’s something that comes back to you,” said Nellie Beno of Tselani-Cottonwood. “When you’re small, you don’t think about it.”

"Finding" Folsom

Homolovi Ruins Closure Looms, New Perspectives on the Hohokam, Chaco Chocolate

Southwest Archaeology Today – A Service of the Center for Desert Archaeology

- Homolovi Ruins on List of Recommended Closures: Arizona officials are recommending closures of five state parks immediately and three more in coming months because of midyear budget cuts made to eliminate a revenue shortfall. The parks recommended for closure include the Homolovi Ruins State Park in Winslow.

- Salazar Cancels Drilling Leases: Interior Secretary Ken Salazar on Wednesday canceled leases to drill for gas and oil on 77 parcels of public land in Utah. The leases, which cover more than 100,000 acres, including lands near Arches and Canyonlands National Parks, were auctioned in the last weeks of the Bush administration. They were among 11th-hour actions taken by the Bush Interior Department that have been criticized by environmental groups and are being reviewed by Obama officials.

- Exhibit Opening, “Circles of Life: Katsina Imagery in Hopi Basketry.” February 7–July 3, 2009 at the Arizona State Museum. The importance and impact of the katsina [kachina] religion is pervasive in Hopi culture.

Historic pieces and the work of eight contemporary weavers demonstrate the continuing vitality of this art form. Enjoy a historic overview of the Hopi basket-making traditions, techniques and types, and learn how to "read" and identify distinguishing katsina iconography.

- Lecture Opportunity (Phoenix): Center for Desert Archaeology Preservation Archaeologist Jeffery Clark will present "What Became of the Hohokam," in which he will present the results of an extensive research project into the demise of the Hohokam. This research used information from 4000 major sites in the Coalescent Communities Database, 29 test excavations in the San Pedro River Valley, and an analysis of extensive collections from Arizona Museums. The talk starts tonight, Jan 8th, at the Pueblo Grande Museum Community Room, 4619 E. Washington Street, at 7:30 pm, as part of the monthly meeting of the Phoenix Chapter of the Arizona Archaeology Society.

- More Ancient Comet Impacts? Multiple comet impacts around 1500 years ago triggered a "dry fog" that plunged half the world into famine. Historical records tell us that from the beginning of March 536 AD, a fog of dust blanketed the atmosphere for 18 months. During this time, "the sun gave no more light than the moon", global temperatures plummeted and crops failed, says Dallas Abbott of Columbia University's Lamont-Doherty Earth Observatory in New York. The cause has long been unknown, but theories have included a vast volcanic eruption or an impact from space. Now Abbott and her team have found the first direct evidence that multiple impacts caused the haze.

- Recent Findings in the Amazon Point to Unique Social Adaptations to Life Within Rain Forests: Rainforests are often thought of as virgin habitats: in other words, pristine ecosystems unaltered by the hand of man. A moment’s thought shows that this cannot truly be so. People do live in rainforests, and where people live they must alter things. But the fact that those who live there these days tend to make their living by hunting wild animals and gathering wild plants may suggest that Homo sapiens could, in principle, be just another forest species—a natural part of the ecosystem that alters it only to the extent that any species inhabiting it would. To that extent, the forest is still “virgin”. In the world’s largest rainforest, though, this argument no longer holds. The past few years have brought evidence suggesting that parts of the Amazon forest were settled and farmed before Europeans arrived in the area.
