... recent excavations at Gault are part of a growing list of digs contributing new evidence that not only asserts that there were other peoples in the Americas at the same time as those who made Clovis points, but that humans had reached these lands earlier, and possibly by different routes. At the conference, when it was Collins’ turn to speak, he said just that. “By the beginning of the Younger Dryas [a 1,300-year cold snap that began about 12,800 years ago], this was already a fairly crowded archaeological landscape.” Archaeology.org

I have to wonder how many prehistoric sites are submerged miles out from the present coastlines considering the fluctuation of sea levels occurring during the glacial periods of the last ice age.
Our main point was that at the end of the last Ice Age in North America there seemed to be two cultural entities of roughly equal antiquity present which were represented in the archaeological record by distinctive stone tools, e.g. projectile points: one hallmarked by thick-bodied unfluted, lanceolate projectile points and the other by thin-bodied, lanceolate projectile points.
A Power Point Presentation about a projectile point style being employed as a cultural and chronologic diagnostic over an extensive geographical range and the interesting picture/possibilities this application presents.
Mike Kunz wrote and gave this presentation at the 38th annual meeting of the Alaska Anthropological Association (March 9-12, 2011).
Tony Baker, John Garrett and Joshua Ream contributed images of the Clovis, El Jobo, and Haskett points.;
All are: relatively large, thick bodied, well made, heavily edge-ground, unfluted lanceolate forms, with convex bases (if not it's because the base has been damaged or reworked) with the blade expanding from the base to a point beyond half its length, re-sharpening of broken points is extremely common. All except Agate Basin are as old or older than Clovis. It is interesting that at this time, the oldest sites associated with these points are in South America with antiquity of sites incrementally decreasing northward to the Arctic. This seems odd to me as I think the weight of evidence indicates Alaska as being the point of entry for humans into the New World. In my opinion this suggests several possibilities; evidence that would clarify the situation remains undiscovered and/or lies beneath the coastal waters of Alaska and the Northwest Coast where it currently is inaccessible; and/or the associations between the radiocarbon dates and the cultural manifestations at the South American sites are in error or, God forbid, people actually were in South America first.

Right on peter v,
I put it together while doing laundry this morning.
The south to north distribution of dates is very interesting, with the older dates being further south.
In February 2014, the original hypothesis was revived based on a more thorough genetic study. Researchers examined the entire genome, including the plasmid genome and concluded that American specimens were most closely related to wild African variants and could have drifted over the ocean several or many times as long as 10,000 years ago.
Bottle gourd, one of the most cross-culturally ubiquitous crops, had a pan-tropical distribution by the beginning of the Holocene. Our findings overturn a major component of the current model for bottle gourd’s early global dispersal, specifically regarding how it entered the Americas. Our findings also indicate that the domestication process itself took place in a diffuse pattern throughout the bottle gourd’s New World range, explaining early and nearly contemporaneous use of bottle gourds in North, Central, and South America. Bottle gourd’s weedy growth habit and the diffuse domestication pattern also suggest that early cultivation were probably not restricted to known centers of domestication. It is likely, however, that domesticated phenotypes emerged in these centers alongside food crops.
Bottle gourd (Lagenaria siceraria) was one of the first domesticated plants, and the only one with a global distribution during pre-Columbian times. Although native to Africa, bottle gourd was in use by humans in east Asia, possibly as early as 11,000 y ago (BP) and in the Americas by 10,000 BP. Despite its utilitarian importance to diverse human populations, it remains unresolved how the bottle gourd came to be so widely distributed, and in particular how and when it arrived in the New World. A previous study using ancient DNA concluded that Paleoindians transported already domesticated gourds to the Americas from Asia when colonizing the New World [Erickson et al. (2005) Proc Natl Acad Sci USA 102(51):18315–18320]. However, this scenario requires the propagation of tropical-adapted bottle gourds across the Arctic. Here, we isolate 86,000 base pairs of plastid DNA from a geographically broad sample of archaeological and living bottle gourds. In contrast to the earlier results, we find that all pre-Columbian bottle gourds are most closely related to African gourds, not Asian gourds. Ocean-current drift modeling shows that wild African gourds could have simply floated across the Atlantic during the Late Pleistocene. Once they arrived in the New World, naturalized gourd populations likely became established in the Neotropics via dispersal by megafaunal mammals. These wild populations were domesticated in several distinct New World locales, most likely near established centers of food crop domestication.

I wonder if anyone has done an anthropology study to see if calabashs are still washing ashore? If they did back then they would still be doing so today. Old folks in fishing villages would be the ones to ask.
