Has there been any peer review of this archaeology  study?It contains a significant number of anomalies.For example:Level H,[C14,31-29Ka] includes feature 19--rocks >30cm in size form a semi-circle with burnt material [ash,charcoal and wood] and the" hearth "area exhibits appreciably greater burn marks than the adjacent surface,[page 453].Nearly half the lithic material has a foreign source.The latter might [?] be attributed to mixing.However the evidence for the dated hearth is more difficult to discount.Has anyone read the book?

MacNeish published "Late Pleistocene Human Friction Skin Prints from Pendejo Cave, N.M"., American Antiquity 61 (2):357-376). There might be some comments on that paper.

Unfortunately I have not read the book (yet), still waiting for a reasonably priced used copy to show up.

I haven't read the book, either.  But there is a critical review in:

Dixon, E.J. (1999). Bones, Boats, & Bison: Archaeology and the First Colonization of Western North America. Albuquerque: University of New Mexico Press.

from which the following is abstracted verbatim:
Quote
          The cave was occupied by humans during Archaic (later than circa 8,000 B.P.) And possibly Paleoindian times (between 11,500-8,000 B.P.).  However, the evidence for occupation prior to 11,500 B.P. rests on the discovery of fractured and modified bones of Pleistocene animals, human fingerprints and handprints preserved in fire hardened clay, and burned zones interpreted as hearths or culturally generated fires.  The cave deposits contain seven to nine major, and many more minor, periods of packrat occupation.  Packrat nests contain large amounts of vegetation including grasses, sticks, twigs, and other organic debris.  Many of the burned zones thought to be cultural in origin are actually burned packrat middens. They were probably ignited by noncultural fires spreading into the cave from adjacent areas.  These burned areas contain charred macrofossil remains that include packrat feces and other packrat midden material and do not appear to be anthropogenic (pp. 79-80).

          To compound the interpretive difficulties at Pendejo, the deposits have been extensively bioturbated (the churning or mixing of sediments by animals or plants (Dincauze 1997) during thousands of years of packrat nesting and burrowing.  Despite descriptions suggesting the stratigraphic units are well defined, not mixed, and that they demonstrate “acceptable geological and stratigraphic integrity” (Chrisman et al. 1996:362-64, 373; Chrisman et al. 1997), many units have been repeatedly crosscut by rodent burrowing and nesting (Stafford, personal communication 1995).........

........In the absence of clearly identifiable bone tools, such as awls or projectile points, a complex taphonomic setting such as Pendejo Cave requires detailed bone by bone description and analysis that analytically excludes other possible means of noncultural alteration.  Although Pendejo Cave contains a wealth of archaeological and paleoecological data, evidence of human activity prior to 11,500 B.P. cannot be documented satisfactorily.  Noncultural taphonomic processes, noncultural fires, bioturbation, weathering, and rockfall best explain the earliest suite of specimens and other evidence from Pendejo Cave (p. 81).

Dixon (see reference in previous post) says this about the human "prints"
Quote
          The identification of human skin impressions and fingerprints preserved in clay has been questioned by other researchers.  They suggest the preserved print ridges are not human prints based on the number of ridges in a given area (Shaffer and Baker 1997).  However, Chrisman (1997) argues that the prints have been distorted because the photographs are of curved surfaces and because baking and drying the clay after the impressions were made modified them.  Even if the prints are legitimate artifacts, the extensive bioturbation at the site makes their associations with Pleistocene age botanical and faunal specimens questionable (pp. 80-81).

Dixon says this about the "modified bones":
Quote
          There are also equally plausible noncultural explanations for the modified Pleistocene bone, such as dessication fracturing, carnivore fracture and flaking, rodent gnawing, rockfall, and rubble scaring [sic.].  Jagged blocks of dolomite that have fallen from the ceiling of the cave are large enough to fracture, flake, or scar any bone lying on the surface.  Many of these large blocks have fallen a distance of 1-3 m (3-10 ft), and some rocks weigh more than 40 kg (100 lb).  Johnson and Shipman (1993) conducted scanning electron microscopic analysis of a sample of bone from the Pleistocene levels were not able to identify evidence of cultural modification on any of the specimens (p. 81).

Lacking adequate knowledge of Pendejo Cave, I have no opinion of my own on these controversies.

The book contains detailed reports on numerous studies.The evidence for human occupation to ca 12.4Ka is reasonably sound-prior to that date the data is equivocal and the expert analyses are largely qualified.Thanks for the comment on possible natural fires in the cave.It  provides a logical answer to my primary question and fits the facts.There is a lot of information in the text .It is going to take considerable effort to collate all the different disciplines.

Robert,
Does the book discuss the same modified bones that are shown in the web link?

It is a little hard for me to imagine a natural process of a falling rock driving a  limestone wedge 1.5 cm axially into the end of a horse phalange. Or some crafty carnivore managing to push a pointed bone into the medullary cavity of a larger bone by gnawing on it. Maybe those Dire Wolves were much smarter than we give them credit.

Allan,
There are lengthy technical reports on the modified bones,hair,finger prints,validity of the lithic artifacts,woven material,etc.Currently just doing a quick skim of the 500+ pages.
Will post a comment on the modified bones,when I have throughly read that section.

Regarding you post scriptum, thanks for bringing up the Yukon stuff. I can assure you that Richard 'Scotty' MacNeish was definitely not one to shy away from New World archaeological evidence predating 12,000 years ago. Although, he admittedly managed to go overboard a few times!
