In the summer of 2016, the BLM Burns District continued its partnership with the University of Oregon Museum of Natural and Cultural History and the Oregon Archaeological Society and conducted archaeological excavations at the Rimrock Draw Rockshelter site in southeastern Oregon.
The site, discovered in 2009 by BLM Archaeologist Scott Thomas, has hosted archaeology field schools since 2011. In 2015, it became internationally known after archaeologists found a small agate tool stone under a layer of volcanic ash from a volcanic eruption about 15,800 years ago.
This tool suggests one of the oldest known human occupations in the western United States.
The 2016 excavations encountered significant rock and boulder debris, resulting from at least two occasions of portions of the rock wall calving or breaking off – probably around 8,000 and 10,000 years ago. These rocks limited access to the ground beneath them, and many were removed only after drilling and splitting reduced them to removeable sizes.
In coordination with the BLM’s Scott Thomas, Dr. Patrick O’Grady with the University of Oregon Museum of Natural and Cultural History directed excavations for the fifth year in 2016, and Jordan Pratt, graduate student at Texas A&M University, served as the excavation’s site supervisor. Volunteers from the Oregon Archaeological Society, students from the University of Oregon, and archaeologists from the BLM conducted the excavations.
My draw weight here is 58,191 and my texture maps are so small (aside from my skin, only one is 512x512 most of my textures are 64x64 or 128x128) that my avatar uses less VRAM to render than most individual attachments on other avatars. If most avatars were about this efficient you'd experience much higher FPS and much less lag in SL, even in packed sims.
A retractable draw gate on the Torre dell'Elefante (1307) controlled access to medieval Cagliari (Sardinia), Italy, from the lower town. The sculpture of an elephant to the left of the gate gave the tower its name.

The evil that is in the world always comes of ignorance, and good intentions may do as much harm as malevolence, if they lack understanding. On the whole men are more good than bad; that, however, isn't the real point. But they are more or less ignorant, and it is this that we call vice or virtue; the most incorrigible vice being that of an ignorance which fancies it knows everything and therefore claims for itself the right to kill. There can be no true goodness, nor true love, without the utmost clear-sightedness. (Albert Camus)

Near the Rimrock Draw Rockshelter outside of Riley, Oregon, archaeologists recently discovered evidence suggesting one of the oldest known human occupations in the western United States.
Archaeologists with the Bureau of Land Management (BLM) and the University of Oregon Archaeological Field School have been excavating at the Rimrock Draw Rockshelter since 2011.
Their discoveries have included a number of stone projectile points and tooth enamel fragments likely belonging to a prehistoric camel (Camelops sp.) that became extinct approximately 13,000 years ago.
But what has the archaeological community most excited is a small stone tool found below a layer of volcanic ash.
Near the bottom of a 12-foot deposit, archeologists discovered a layer of ash that was identified as volcanic ash from a Mt. St. Helens eruption about 15,800 years ago.
Beneath the layer of volcanic ash, archaeologists discovered a small orange agate tool believed to have been used for scraping animal hides, butchering, and possibly carving wood. A blood residue analysis of the tool revealed animal proteins consistent with bison, the most likely species being Bison antiquus, an extinct ancestor of the modern buffalo.
“The discovery of this tool below a layer of undisturbed ash that dates to 15,800 years old means that this tool is likely more than 15,800 years old, which would suggest the oldest human occupation west of the Rockies,” said Scott Thomas, BLM Burns District archaeologist.
Presently, Oregon’s Paisley Cave, also managed by the BLM, is considered home to the earliest known residents of North America based on human physical evidence. In 2008, a team of archaeologists, led by Dr. Dennis Jenkins with the University of Oregon's Museum of Natural and Cultural History, discovered coprolites - dried feces - containing human DNA dated over 14,000 years old.
Dr. Patrick O’Grady, with the University of Oregon Archaeological Field School, has been directing the Rimrock Draw Rockshelter excavations since they began. “When we had the volcanic ash identified, we were stunned because that would make this stone tool one of the oldest artifacts in North America. Given those circumstances and the laws of
stratigraphy, this object should be older than the ash,” said O’Grady. “While we need more evidence before we can make an irrefutable claim, we plan to expand our excavation this summer and hopefully provide further evidence of artifacts found consistently underneath that layer of volcanic ash. That’s the next step.”
The University of Oregon Archaeological Field School, in partnership with the BLM and volunteers from the Oregon Archaeological Society, will be begin its fifth season this summer, offering students, researchers, and volunteers invaluable field experience. Stan McDonald, BLM Oregon/Washington lead archaeologist, explained the potential this discovery has for the archaeological community.
“For years, many in the archaeological field assumed that the first humans in the western hemisphere were the Clovis people – dating to around 13,000 years ago. While a handful of archaeological sites older than Clovis cultures have been discovered in the past few decades, there is still considerable scrutiny of any finding that appears older,” McDonald explained.
“With the recent findings at Rimrock Draw Shelter, we want to assemble indisputable evidence because these claims will be scrutinized by researchers. That said, the early discoveries are tantalizing.”

(My style has changed a little...yea?)
I think it's smart to save every layers, so that you can, and you'd better see this ^^
