Documentation of a Collection of Archaeological Materials from the Millsey Williamson Site (41RK3), A Historic Nadaco Caddo Settlement

The Millsey Williamson site (41RK3) is a well known historic 18th century Nadaco Caddo site on Martin Creek in Rusk County, Texas. It is one of a number of 18th and early 19th century Kinsloe phase sites in the middle Sabine River basin apparently affiliated with the Nadaco Caddo settlement of the region. An unknown number of historic Nadaco Caddo burials have been excavated at the site over the years, especially along the western part of the terrace landform above Martin Creek, now marked by the Martin Lake shoreline. There has been intensive collecting activities at Millsey Williamson since Martin Lake was built more than 30 years ago. The collection we document here came from the shoreline in the general area of the other Nadaco Caddo burials reported from Millsey Williamson

The Pine Saddle site (3PL1080) in the Ouachita Mountains, Polk County, Arkansas

Novaculite was procured and knapped by aboriginal Indian populations living in southwestern Arkansas for thousands of years, and there are numerous prehistoric novaculite quarries in the Ouachita Mountains. In Late Archaic times. this desirable material was widely traded and exchanged with other groups to the south, east, and west, particularly with the peoples living at the Poverty Point site and environs in the lower Mississippi valley in northern Louisiana. Later groups such as the Caddo also made considerable use of this material, since it was in their traditional homelands, and many habitation sites and mound centers in the region contain quantities of novaculite lithic debris and tools. Other local materials were also chosen for lithic tool manufacture, such as Big Fork chert, a distinctive black chert. Abundant amounts of novaculite and Big Fork chert are also found apparently in nondomestic Caddo contexts on lithic workshops and camp sites in the Ouachita Mountains, and one such site is discussed in this article

Certain Caddo Sites in the Ouachita Mountains of Southwestern Arkansas

In the last few years, we have had the opportunity to study a number of prehistoric Caddo Indian sites in the Ouachita Mountains of southwestern Arkansas through conducting archeological surveys of more than 2700 acres at three lakes constructed and managed by the U.S. Army Corps of Engineers, Vicksburg District. The three lakes are DeGray Lake on the Caddo River, Lake Ouachita on the Ouachita River, and Lake Greeson on the Little Missouri River. Our purpose in this article is to summarize the archeological character of the prehistoric Caddo sites in these three different parts of the Ouachita Mountains. We focus in particular on the material culture record of these prehistoric Caddo settlements—especially on the ceramic sherds found on them—and discuss when these sites may have been occupied by Caddo peoples

The Clay Ball Site in the Upper Neches River Basin of East Texas

The Clay Ball site is an ancestral Caddo site believed to be located in the upper Neches River basin in East Texas. The site is notable for its series of small, square vessels with Frankston phase (ca. A.D. 1400- 1650) engraved motifs, as such vessel forms have not been previously documented in studies of Frankston or later Allen phase (ca. A.D. 1650-1830) vessel assemblages. The unique ceramic vessels from the site were excavated by Buddy C. Jones, and although his main site collecting and excavation work was in the mid-Sabine River basin, he did excavate several sites in the upper Neches River basin in Anderson, Cherokee, and Smith counties. Unfortunately, Jones left no notes or records associated with the Clay Ball site that would allow us to either ascertain the contextual relationship of the various features at the site where they were excavated, nor for that matter even provide a locational description of the site

The Wa\u27akas Site (41CP490) at Lake Bob Sandlin, Camp County, Texas

The Wa\u27akas site (meaning Cow in the Caddo language) is located on a small toe slope (330ft. amsl) overlooking a small and unnamed tributary to Big Cypress Creek. The channel of Big Cypress Creek lies about 1 km to the north. The toe slope landform is normally inundated by the waters of Lake Bob Sandlin but became exposed during an episode of lowered water levels (about LO feet below the normal pool elevation of 337ft. amsl) at the lake due to drought conditions from late 2005 to early 2007. A large number of prehistoric artifacts were exposed on the landform over a ca. 2500 square meter area (0.6 acres), according to the site form, among them 490 sherds, several arrow points and dart points, as well as some pieces of lithic debris. The site was then inundated again, but a renewed drought in 20 II re-exposed the site. A moderately-sized collection of artifacts found at the site, primarily Caddo pottery sherds, at that time have been recently documented, and are reported on in this article

Pulling Pinned Polymers and Unzipping DNA

We study a class of micromanipulation experiments, exemplified by the pulling apart of the two strands of double-stranded DNA (dsDNA). When the pulling force is increased to a critical value, an ``unzipping'' transition occurs. For random DNA sequences with short-ranged correlations, we obtain exact results for the number of monomers liberated and the specific heat, including the critical behavior at the transition. Related systems include a random heteropolymer pulled away from an adsorbing surface and a vortex line in a type II superconductor tilted away from a fragmented columnar defect.Comment: 4 pages, 1 EPS figure; revised references and very brief discussion of order of the transition added; to appear in Phys.

Documentation of Additional Vessels from the Johns Site (41CP12), Camp County, Texas

The Johns site (41CP12) is a Titus phase cemetery in the Prairie Creek valley in the Big Cypress Creek stream basin of the Northeast Texas Pineywoods. The Caddo artifacts from the site are from the Robert L. Turner, Jr. and Tommy John collections. Both men are current residents of Camp County, Texas. total of 35 Late Caddo (ca. A.D. 1400-1680), Titus phase, burials were excavated between May 1966 and December 1984 at the Johns site. The first 19 burials were excavated by Tommy Johns and Robert L. Turner, Jr., and Johns continued to excavate burials at the site until 1984. No single map of the plan of the Johns site cemetery exists in the available notes, but enough information is provided to reconstruct the arrangement and extent of the burial interments. The burials occur in a number of east-west rows, with the head of the deceased oriented almost always to face to the west. The deceased were placed in long, narrow, and relatively deep burial pits in an extended supine position, with funerary offerings generally placed along both the sides of the body and at the feet. Funerary offerings consisted of ceramic vessels (3-16 vessels per burial), ceramic pipes, arrow points (usually in quivers), celts, smoothing stones, as well as scrapers and other chipped stone tools. All of the burials have ceramic vessel funerary offerings, but only a small proportion had either ceramic pipes (25.7% of the burials), arrow points (62.9% of the burials), celts (17.1% of the burials), or other stone tools (17.1% of the burials) placed in the burial pit. In the summer of 2009, the Robert L. Turner, Jr. vessel and pipe collection and the Tommy Johns collection of vessels, pipes, celts, and arrow points were fully documented from the Johns site. A detailed description of each ceramic vessel or ceramic pipe was made for documentation purposes, accompanied by drawings appended to vessel documentation forms (on file, Archeological & Environmental Consultants, LLC files in Austin, Texas), where needed, of ceramic vessel decorative motifs or pipe morphology to supplement the artifact descriptions. Analysis notes and photographs were also obtained on the arrow points, celts, and other stone artifacts from a number of burials in the Johns collection. A total of 277 ceramic vessels were documented in the Turner and Johns collections from the Johns site. Subsequent to the completion of the published report, Tommy Johns located six additional vessels from the Johns site cemetery in his collection, and these vessels were documented in January 2010. This article provides information on the six previously undocumented vessels from the Johns site, increasing the total number of vessels to 283.1 With the larger sample of 283 vessels, the vessels from the Johns site are dominated by engraved fine wares (68.1%). Utility wares comprise 25.5% of the ceramic vessel mortuary offerings, and plain wares another 6.4%
