"Researchers had long thought that the sophisticated skills needed to survive winters where the temperature reaches minus 70 degrees and soil freezes to three feet below the surface came only after the appearance of anatomically modern humans 150,000 years ago. The discovery came after scientists found fist-sized stone tools at Diring Yuriakh, an ancient quarry located 300 miles south of the Artic Circle in Siberia. Tests of the surrounding soil determined the tools were somewhere between 260,000 and 370,000 years old. The news could greatly affect how scientists view human development. Or, just as important, it shows even early humans would live in completely inhospitable places."Maybe they made it to here too:

“...But the ultimate proof came when scientists found a debris pile at what may have been a toolmaker’s work station. In the debris pile were distinctive quartz flakes. Some of the flakes could be fitted exactly into the sharpened faces of some of the stone tools, said Waters.”
WOW! GOTCHA!

Nevertheless, although it will take time, the pre-Clovis Monte Verde site in Chile and the 260 ka Diring site in Siberia may well provide a "stepping stone" for mainstream archaeological acceptance of the Calico site.BRILLIANT POST AND THREAD, going back to read it all now, thanks!

Just HOW much did this CRAP co$t US, the damn taxpayers, what a bunch of useless studies.... What part of it is invalid, in your opinion? If it's valid, it has obvious value, training new scientists as well as refining models that can be used for medical, botanical, etc., purposes...not to mention serendipitous spinoffs (the ROI is excellent, and is one of the few areas where the federal government has a role). If you believe it's not valid, please share your critique.
