Current Research: Building A Corpus Of Crockett Curvilinear Incised Vessels, Duncan P. Mckinnon Jan 2019

Current Research: Building A Corpus Of Crockett Curvilinear Incised Vessels, Duncan P. Mckinnon

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

As presented in an earlier report (McKinnon 2018), I have been compiling, with the help of several Caddo researchers, a comprehensive multi-state database of Caddo vessels (now close to 15,000). The on-going goal is to evaluate landscape scale social interactions and interregional relationships using this growing ceramic database. Some initial explorations have been productive in evaluating relationships between proposed Caddo communities (archaeological phases) and I suggest that these exercises have offered insights into Caddo interaction, identity, and ideological exchange in a visual and (continually) comprehensive way (McKinnon 2011, 2016).

ln December 2017, AmaTerra Environmental lnc. conducted an intensive archeological survey of 41CS125, a previously reported ancestral Caddo site at Lake Wright Patman in Cass County, Texas. The work was done at the request of the U. S. Army Corps of Engineers, Fort Worth District in advance of a proposed bank stabilization pro}ect. The site was occupied from the Late Paleoindian period through historic times with extensive occupations during the Formative to Early Caddo and Late Caddo periods. Artifacts recovered in the investigations included both arrow and dart points, lithic debitage, bifaces, ground stone, a celt fragment, pitted stone ...


A Preliminary Comparison Of Two Caddo Mound Sites In Southwest Arkansas, Mary Beth D. Trubitt Jan 2019

A Preliminary Comparison Of Two Caddo Mound Sites In Southwest Arkansas, Mary Beth D. Trubitt

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Previous Arkansas Archeological Survey excavations at the Hedges site in the Ouachita River valley and the Hughes site in the Saline River valley uncovered evidence of burned structures adjacent to the mounds. An overview of the artifact analyses indicates that the sites were roughly contemporaneous, with intensive use by ancestral Caddo Indians during the Late Caddo period, between the AD 1400s and 1600s. This presentation summarizes the research .ftndings to emphasize comparisons in timing, activities, and community plans.


In Between Two Worlds: Past Perspectives On The Neosho Phase (A.D. 1400-1650), Paige Ford Jan 2019

In Between Two Worlds: Past Perspectives On The Neosho Phase (A.D. 1400-1650), Paige Ford

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The Neosho phase (A.D. 1400-1650) in northeastern Oklahoma, northwestern Arkansas, southwestern Missouri, and southeastern Kansas represents Late Pre-contact peoples engaged in widespread trade from the Plains to groups in the southeastern United States. The phase has confounded researchers since its de.ftnition, although debates mainly concern one of two main questions concerning the identity of Neosho peoples: origins and cultural af.ftliation. Most research to date has focused simply on the question of emergence. Early in these debates, Orr (1946) suggested that Neosho peoples represented one or more plains-oriented groups that had migrated into the area, while Wyckoff (1980 ...


First Test Of Habitat Suitability Models For The Davy Crockett National Forest, Robert Z. Selden Jr., David A. Foxe, Juanita D. Garcia Jan 2019

First Test Of Habitat Suitability Models For The Davy Crockett National Forest, Robert Z. Selden Jr., David A. Foxe, Juanita D. Garcia

CRHR: Archaeology

The test for this suite of models was conducted as a double-blind survey since neither the United States Forest Service personnel (excepting Garcia) nor the participants were provided with any information regarding the model in advance of testing. Input from the model was shared with the crew the day after each location was tested. Enlistment of the double-blind survey method aids in reducing survey bias. Collection of data for this project begins with the stratified random sample. The sample consists of random locations throughout compartments of the Davy Crockett National Forest. Those locations not visited in the first test of ...


Caddo Pottery From Eight Sites In The Middle Ouachita River Valley, Mary Beth D. Trubitt Jan 2019

Caddo Pottery From Eight Sites In The Middle Ouachita River Valley, Mary Beth D. Trubitt

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Documentation and analysis of ceramic vessels in the Joint Educational Consortium's Hodges Collection has focused on reconstructing grave lots based on notes left by amateur archeologist Vere Huddleston in the 1930s and 1940s. Despite problems with the data, we can glean useful information from this collection. Here, l describe Caddo pottery and other artifacts in grave lots from eight sites in Clark and Hot Spring counties of west-central Arkansas. l then order the grave lots in time based on stylistic and technological characteristics (seriation) to re.ftne the ceramic chronology of the Middle Ouachita River valley and compare mortuary ...

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

In June 2017, Jenna Bradley and Robert Cornett were boating down the Red River in northern Caddo Parish, Louisiana, when they noticed an unusual log protruding from a sandy bank near the town of Belcher. After realizing that it was a dugout canoe, they contacted the Louisiana Department of Wildlife and Fisheries, and eventually word of the find was transmitted to state archaeologist Chip McGimsey at the Louisiana Division of Archaeology. The following day, Bradley and Cornett led Jeffrey Girard and Jameel Damlouji of the Louisiana Archaeological Society to the site. It was obvious that it was a dugout canoe ...


Current Research: Organic Residues On Engraved Vessels From Ancestral Caddo Sites In East Texas, Timothy K. Perttula Jan 2019

Current Research: Organic Residues On Engraved Vessels From Ancestral Caddo Sites In East Texas, Timothy K. Perttula

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

In the course of recently documenting ancestral Caddo ceramic vessels from sites dating to Late Caddo period Titus phase contexts (ca. A.D. 1430-1680) in East Texas, specifically on sites in the Big Cypress Creek and Sabine River basins, I have encountered a significant number (ca. 9.6 percent) of more than 1790 engraved fine ware vessels that have an exterior organic residue (Table 1), including carinated bowls, compound bowls, jars, bowls, and even bottles. In some cases, the exterior residue on certain carinated bowls and compound bowls is so thick that the engraved design is obscured and almost completely ...

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

In 2012, Perttula requested permission from to the Caddo Nation of Oklahoma's Repatriation Committee to analyze small samples (ca. 1-2 grams of ceramic paste, or sherds ca. 1-2 square centimeters in size) from the paste of five vessels from Features 31 and 95 at the Washington Square Mound site (41NA49) (Perttula et al. 2010) in East Texas to identify residue traces of the Caddo's use of peyote in the 13th-15th centuries A.D. The Caddo Nation of Oklahoma gave their permission to conduct these ceramic vessel residue studies.


Current Research: Spiro And Caddoan Connections On The Northern Frontier Of Southwest Missouri, Jack H. Ray Jan 2019

Current Research: Spiro And Caddoan Connections On The Northern Frontier Of Southwest Missouri, Jack H. Ray

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Excavations during the construction of Table Rock Lake in the late 1950s resulted in a proposition that there was a colonization of peoples into the upper White River drainage from Caddoan areas to the southwest (Chapman 1980; Chapman et al. 1960). This colonization, which resulted in the formulation of the Loftin phase, is widely accepted today (O'Brien and Wood 1998; Perttula 1983, 1989; Sabo and Early 1990). Later, James Brown (1984) exposed the myth that the southwestern Ozarks was a cultural enclave that lagged behind Mississippian developments in other parts of the Trans-Mississippi South.

Current Research: Renewing Research On Holman Springs (3sv29), A Caddo Saltworks In Western Arkansas, Carl G. Drexler, Fiona M. Taylor

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The Holman Springs site (3SV29) lies in western Sevier County, Arkansas, near the Oklahoma border. It is, along with Bayou Sel (3CL27), one of two major excavations of Caddo saltworks that has not been substantially reported. Excavated between 1984 and 1986 by the Arkansas Archeological Society during their annual Training Program digs, the collections remain at the Arkansas Archeological Survey's research station (ARAS) at Southern Arkansas University (SAU) in Magnolia.

The collections lay dormant for many years. Then, in 2015, the station staff revived the project and started moving it towards completion. This is a daunting challenge, given the ...

Middle Caddo Whole Vessels From The Ferguson Site (3he63), Pritam Chowdhury

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The Ferguson site (3HE63) is a Caddo ceremonial center in Hempstead County, Arkansas. The Arkansas Archeological Survey and Arkansas Archeological Society excavated Ferguson between 1972 and 1974, under the direction of Dr. Frank Schambach. The site has a middle Caddo Haley phase (A.D. 1200- 1400) component consisting of two mounds, several structures, and a small cemetery area, set atop a 2-acre Woodland period Fourche Maline village. One of the mounds included several elite Caddo shaft graves rich with ceramic artifacts. My recent research with Ferguson site collections included a metric and stylistic analysis of whole vessel ceramics from the ...

Current Research: Toward A Collaborative Development Of A Truly Comprehensive Multi-State Material Culture Database, Duncan P. Mckinnon

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Throughout the past several years, I have been compiling, with the help of several Caddo researchers, a comprehensive multi-state database primarily composed of whole Caddo vessels from published excavations, private collections, and archaeological reports. At present, the database contains over 13,000 vessel entries from over 500 sites ranging from a single vessel recorded at a site to hundreds. Over the years, the database has evolved to contain, where applicable, attribute fields on type, variety, motif designs (largely using the Glossary of Motifs published in the Spiro shell engravings, collegiate assignment, form, temper, decorative method (incised, brushed, etc.), context (burial ...


Current Research: Ceramic Production And Distribution During The Formative Caddo Period: A Stylistic And Provenance Investigation Of The Arkansas River Valley, Shawn Lambert Jan 2018

Current Research: Ceramic Production And Distribution During The Formative Caddo Period: A Stylistic And Provenance Investigation Of The Arkansas River Valley, Shawn Lambert

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The Formative Caddo Period (A.D. 850-1100) of eastern Oklahoma was marked by dramatic material and ritual changes, culminating in the construction of aggregated villages and ceremonial centers. Formative Caddo groups are notable for their highly complex and ritually-charged ceramic vessels that were unlike anything archeologists have seen in the American Southeast. Tracing the rapid development and spread of this early fine ware assemblage across a variety of social, ritual, and mortuary contexts is key to understanding the shared religious and ritual traditions of the pre-Columbian Arkansas River valley and surrounding Coastal Plain drainages. Yet despite nearly 60 years of ...


The Effects Of Horses And Raiding On The Salt Industry In Northwest Louisiana, Paul N. Eubanks Jan 2018

The Effects Of Horses And Raiding On The Salt Industry In Northwest Louisiana, Paul N. Eubanks

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

When French explorers first arrived in northwest Louisiana, the local Caddo Indians had already earned a reputation for being important players in the salt trade. Likewise, many western Caddo groups living near the southern Plains were known for their involvement in the horse trade. In the first part of this paper, the relationship between the local salt industry and the introduction of the horse is considered. It is suggested that at least some of the salt made in northwest Louisiana was being fed to horses and other livestock acquired either directly or indirectly from the Spanish. In addition to its ...


Ceramic Morphological Organization: Quiddity Of Shape For Hickory Engraved Bottles, Robert Z. Selden Jr. Jan 2018

Ceramic Morphological Organization: Quiddity Of Shape For Hickory Engraved Bottles, Robert Z. Selden Jr.

CRHR: Archaeology

This study expands upon a previous analysis of the Clarence H. Webb collection, which resulted in the identification of two Caddo bottle shapes used in the manufacture of Hickory Engraved (HE) bottles. The current sample of Caddo bottles adduces three-dimensional meshes from the HE specimens in the Webb collection, as well as 14 new meshes from six sites and one collection; all of which fall under the purview of the Native American Graves Protection and Repatriation Act (NAGPRA). Results confirm that HE bottle shape differs significantly by site in some cases, that the two discrete shapes identified in the previous ...


Lithic Morphological Organization: Gahagan Bifaces From Texas And Louisiana, Robert Z. Selden Jr., John E. Dockall, Harry J. Shafer Jan 2018

Lithic Morphological Organization: Gahagan Bifaces From Texas And Louisiana, Robert Z. Selden Jr., John E. Dockall, Harry J. Shafer

CRHR: Archaeology

This study is focused upon an analysis of Gahagan biface morphology and enlists the three largest samples of these bifaces, to include that of the type site (Gahagan Mound) as well as the Mounds Plantation and George C. Davis sites. Results indicate a significant difference in Gahagan biface morphology at the Mounds Plantation site when compared with Gahagan bifaces from the Gahagan Mound and George C. Davis sites. A test of morphological integration indicates that the bifaces are significantly integrated, meaning that those traits used to characterize their shape (blade and base) vary in a coordinated manner. Tests for allometry ...


Beaver Lake Projectile Point, Robert Z. Selden Jr. Jan 2018

Beaver Lake Projectile Point, Robert Z. Selden Jr.

CRHR: Archaeology

This is a Paleoindian Period Beaver Lake projectile point (approx. 10,500-9,500 B.P.) of Ft. Payne chert discovered in Perry County, Tennessee. It is associated with state site number 40PY312 and context of find is a shoreline bank on the Tennessee River near Linden, Tennessee. Site 40PY312 is also associated with hundreds of early stage reduction flakes of Ft. Payne chert. The point is important because of its Paleoindian cultural affiliation of which very little is known, and also by the fact it has been re-purposed from a projectile point to an end-scraper. The re-purposing of projectile points ...


Geometric Morphometrics Of Gary Dart Points From The Davy Crockett National Forest, David A. Foxe, Robert Z. Selden Jr., Juanita D. Garcia Jan 2018

Geometric Morphometrics Of Gary Dart Points From The Davy Crockett National Forest, David A. Foxe, Robert Z. Selden Jr., Juanita D. Garcia

CRHR: Archaeology

Three-dimensional scans of Gary dart points recovered from the Davy Crockett National Forest are employed in tests of basal morphology by site, size (allometry), and asymmetry. Variability in basal morphology for Gary points from sites on the Davy Crockett National Forest is presented and compared to specimens from the published type books. The hypothesis that Gary basal morphology differs between sites containing Woodland-era sand temped ceramics and those where no sand tempered ceramics were recovered is then tested and the results discussed.

The sample includes the Smithport Plain bottles from the Webb collection, and four new bottles: two previously repatriated specimens in the Pohler Collection, and two from the Mitchell site (41BW4) to test whether those specimens align morphologically with the Belcher Mound or Smithport Landing specimens. Results indicate significant allometry and a significant difference in Smithport Plain body and base shapes for bottles produced at the ...


Addressing Survey Bias: Maxent Models And Public Archaeology At The Davy Crockett National Forest, Juanita D. Garcia, Robert Z. Selden Jr., David A. Foxe Jan 2018

Addressing Survey Bias: Maxent Models And Public Archaeology At The Davy Crockett National Forest, Juanita D. Garcia, Robert Z. Selden Jr., David A. Foxe

CRHR: Archaeology

Over the past 30+ years, compliance-based archaeological projects conducted on the Davy Crockett National Forest have yielded an impressive contribution to the archaeological record. However, those efforts were limited to specific survey areas based upon specific needs. To begin to address survey bias and the impact that it can have on site probability models, a stratified random sample of 50 locations was generated for the forest. In early 2018, a public archaeology (Passport-in-Time) project was used to engage interested volunteers who assisted in testing these sample locations. These results, as well as other new data, were added to the maxent ...

Feature-Scale Analysis Using Ground-Penetrating Radar And Low Altitude Prospection At The Collins Mounds Site, Northwest Arkansas, Stephanie M. Sullivan, Tiago Attore

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Geophysical survey and other non-invasive methods are, in some cases, the only options available for archaeological investigation. This is exemplified at the Collins site, a possible Late Woodland to Middle Mississippian period, multi-mound, civic ceremonial center in Northwest Arkansas. The site is located on private property and although excavation is not allowed, non-invasive survey methods are permitted on its northern section. This paper presents the results of a ground-penetrating radar survey over Mounds B, C, and D. The results reveal a number of features that are interpreted as mortuary structures as well as evidence of multiple building episodes over time ...

Morphological Variation In Three-Dimensional Printed Replicas, Robert Z. Selden Jr., Bernard Means, Edward G. Iglesias, Kreg Mosier

CRHR Research Reports

Employed primarily for outreach and education, the three-dimensional (3D) printer used in this analysis provides a means of producing tangible models of fragile and restricted-use specimens for students from a wide variety of disciplines, and is used here to produce prints associated with historic and prehistoric cultural objects. Recognizing that inconsistencies occur in 3D prints due to environmental variables, this exploratory effort was aimed at identifying the geometry that deviates most from the original scan data. A total of five replicas were printed then compared by calculating the gap distance between the nominal (original scan data) and measured data (scan ...
