The last deglaciation was characterized by numerous abrupt climate shifts including the extended Bølling and Allerød warm periods and the Preboreal, Younger Dryas, Older Dryas and Intra-Allerød cold periods, which caused loss of stability across the periglacial landscapes of the Great Lakes region. To date, assessing the possible impact of abrupt late glacial environmental change in this area has been limited by paucity of high-resolution environmental proxies that can be compared to the...
Bluefish Caves Revisited: Testing a Potential Pre-Clovis Site in Eastern Beringia (2023)
This is an abstract from the "Archaeology of Alaska, the Gateway to the Americas" session, at the 88th annual meeting of the Society for American Archaeology. Originally excavated by Jacques Cinq-Mars in the 1970s and 1980s, Bluefish Caves, Yukon Territory, yielded artifacts and faunal remains. Cinq-Mars’s chronology for human occupation at the site dates to as early as ca. 24 ka and has been corroborated by AMS 14C-dated cut-marked bones. These findings support the genetic “Beringian...
Continuing the Search for Pre-Clovis Aged Cutmarked Bones in the Great Basin: Recent Results (2016)
Hockett and Jenkins (2013) suggested that two bones directly AMS dated prior to the Clovis era (ca. > 13,100 calendar years ago) recovered from the Paisley Caves, Oregon, displayed stone tool cutmarks. Since this publication, additional bones were identified as possibly exhibiting cutmarks from Paisley Cave #2. In addition, in the 1950’s Phil Orr recovered a number of burned large mammal bones from Pleistocene-aged deposits in several caves flanking the eastern margins of the Winnemucca Lake...
The First Americans South of the Continental Ice Sheets–Correlating the Late Pleistocene Archaeological and Genetic Records (2016)
There is strong empirical evidence showing that North and South America were occupied before Clovis. This comes from sites such as Monte Verde, Chile, Paisley Caves, Oregon, Schaefer and Hebior, Wisconsin, Page-Ladson, Florida, Debra L. Friedkin, Texas, Wally’s Beach, Canada, and a few others. This evidence places the initial occupation of the Americas at about 15,000 cal yr B.P. Quality chronological data for Clovis still place this complex between 13,000 and 12,600 cal yr B.P. Genetic studies...
The Inglewood Mammoth (Maryland) and Others Like It (2015)
The Inglewood mammoth site near Largo, Maryland, radiocarbon dated in 1982 to 20,000 rcybp, shares some features with other mammoths in North America and Mexico. It had no lithics associated with the bones, and some of the elements had been fragmented. Over 25 years ago I interpreted the bone-breakage as recently done by heavy equipment, but another researcher now interprets it as done by humans in antiquity. I provide a first look at the site’s bone maps, sediment profiles, and other essential...
Modelling Age and Sedimentation Rates at the Page-Ladson Site (2017)
Stone tools and mastodon bones occur in an undisturbed geological context at the Page-Ladson site, Florida. Age models were created for excavation unit 50N/23E and core PLAD-AUC14-4A to estimate age ranges and sedimentation rates. The models were constructed using Bayesian models as implemented in OxCal to calibrate ages, combine equivalent age estimates, exclude outliers, and estimate deposition rates. The models were used to provide age estimates for artifacts recovered from the site,...
New indicators of a "(much) older-than-Clovis" cultural presence at Chiquihuite Cave archaeological site in Zacatecas, Mexico (2017)
The systematic search for ancient human presence in the Zacatecas semi-desert of central-northern Mexico continued with new field explorations and excavations during 2016. A new season at the Chiquihuite Cave was meant to verify the weak signals of older-than-Clovis human presence obtained a few years ago. The new extended excavation inside the high-altitude cave revealed two old, clearly differentiated cultural components that had not been acknowledged before. The upper component is clearly...
Pre Clovis at Topper (38AL23): Evaluating the Role of Human versus Natural Agency in the Formation of Lithic Deposits from a Pleistocene Terrace in the American Southeast (2016)
This paper examines the lithic materials from the presumed pre-Clovis deposits at the Topper Site (38AL23), a Paleoindian quarry and stone tool manufacture site in Allendale County, South Carolina. Prior research at Topper identified flakes and possible chipped stone tools from Pleistocene-aged sediments that predate Clovis, traditionally considered the earliest culture complex in the region. The goal of this study is to document the nature of the pre-Clovis assemblage at Topper, and to explore...
Pre-Clovis Archaeology in the Frontiers of Research:Page-Ladson and the Importance of Submerged Sites to Understanding the First Americans (2017)
Dr. Gruhn has spent her career working in locations that most Paleoindian archaeologists consider to be inaccessible and difficult, maintaining that the story of the First Americans can best be found in well-preserved localities on the geographical and chronological frontiers. Our recent work at the Page-Ladson site in Florida fits well within the spirit of her investigations. Page-Ladson is an inundated terrestrial site with sediments containing lithic artifacts associated with a butchered...

Review of Prehistoric Hunter-Gatherers of the High Plains and Rockies
The South-Eastern Warm Thermal Enclave and Perturbations of the Late Pleistocene (2016)
For decades late Pleistocene climate events prior to the Younger Dryas (Heinrich 0 ~12.9 ka cal BP) were ignored by archaeologists because the Clovis First paradigm implicitly supposed nothing was earlier. Since 2005 attitudes have changed and the importance of understanding the effects of major climate shifts is now important to archaeology. This presentation will focus on the timing of late Pleistocene climate events and the subsequent expressions of habitat change in the Coastal Southeast....
