proof for 130,000-year-old human in California

a reply to: Byrd

You mean other evidence such as this from the yukon.

The stratigraphic position of artefacts of undoubted Pleistocene age found in the Old Crow Basin has long been in question. We report on geological, palaeontological and archaeological excavations and studies there which show that artefacts made by humans occur in deposits of Glacial Lake Old Crow laid down before Sangamonian time, probably during a phase of the Illinoian (=Riss) glaciation. The geological events surrounding and following the deposition of Glacial Lake Old Crow were complicated by a changing lake level, localized soft-sediment flowage, pingo formation and dissolution, and by the colluvial transport of vertebrate fossils and artefacts. Following deepwater stages of the Lake, an environment not greatly different from that of the present is suggested by the excavated vertebrate fauna and by permafrost features, although warming during the succeeding Sangamon can be considered likely. Sangamonian and later phenomena in the Old Crow Basin are referred to briefly; they show that humans persisted in the area for some time.

Nothing new. Russia has dugs up thousands of frozen when the earth had of these and these were still fresh enough to eat, which they did. They were flash frozen [in an instant]. They were still standing on all 4s when there was a serious comic event and the earth got nailed from outer space. You can find all of this is early 1940-1950 records if you are looking. And this event was no 130,000 years ago.

Not even going to get into that discussion here, but the two are completely different.
The climate in SoCal 130k years ago was actually warmer than now, it was nearly subtropical, a caypabara (giant tropical rat)fossil was found in the same bone bed. Besides mastadon and mammoth are very different animals.
But, there is value to your siberia reference, at this point in time humans in siberia are hunting and utiliizing elephant bone, and leaving the same marks on the bones as what was found at Cerruti.

there is a whole lot more to earth history and the cosmos than you are aware. Has nothing to do whether the earth was warmer or not. Frozen animals doesn't prove the earth is old, earth proves the earth is old. There is history of the earth available, true history of you want to learn. Again takes educations at which most people do not know physics or any science.

Anyhow, for anybody still interested, that wasnt driven away by archaeological "biting critique" flys,
The supplemental info (SI)for the paper is where the sometimes tediously technical, but juicy good stuff is. The first SI section is 50+pages of solid science.
Their work is very thorough and well referenced with previous studies that set basis for their conclusions.

One thing I think that is important that they don't get into, where did the pegmatite and andesite cobbles come from?, they arent native to the stream channel, which is all fine sand and silt.
In the SI they go over the distribution of the bones and those of other bone scatters, and they show that the mastadon bone scatter in nearly perpendicular to overall scatter pattern, and there is no size sorting, as with the other scatters, where the smaller pieces are washed farther downstream leaving only the larger fragments. This shows that the pattern of bone and rock fragments was not from the prevailing direction of flow in the stream course.

I have been doing some reading on the geology of the area.
The cobbles are a very important clue. The andesite cobbles are found in an ancient riverbed formed by a Miocene megaflood that flowed north from volcanic regions in Mexico.
The pegmatite in the region is found in a band of solid rock about 30 miles to the east and northeast.
From what i can tell, the two tyoes of cobbles are not found in the same deposits.

I have been looking into the origins of the cobbles,
They are the glue that binds this altogether.
The andesite cobbles come from a miocene deposit laid down by a mega flood from volcanic regions to the south in mexico.
These cobbles are found at the base of the "terraces". The terraces are low bluffs that parallel the coast, a few miles inland.
This site lies on top of the terraces, both uphill and upstream of the nearest source for the cobbles.
The pegmatite cobble originates from a river channel a couple of miles to the north, for that cobble to get there, it had to cross a low ridge, and several small stream and go uphill to get to the site.
Those cobbles are very special indeed.

I think you're confusing modern geology with ancient landforms. When the cobbles were laid down, there was no "low ridge" and "small streams" and "uphill." The ridge was either on a plane with the source of the cobbles or was somewhat lower (gradient) and the streams are undoubtedly of recent origin (as are many in the area), formed after the end of the Ice Age.
