During 2017, the Arkansas Archeological Survey celebrated its 50th anniversary with a series of website postings (http://archeology.uark.edu/who-we-are/50moments/), a forum at the annual meeting of the Arkansas Archeological Society, and a symposium at the annual Southeastern Archaeological Conference in Tulsa. In addition, the Survey made strides in documenting and archiving its history and collections. The Survey’s Henderson State University (HSU) Research Station in Arkadelphia continued to inventory curated artifact collections and scan older paper records and color slides. Trubitt and Cinotto, assisted by volunteers during weekly Archeology Lab Days, are updating the station’s curated collections database with artifact counts and weights, and using identified diagnostic artifacts to revise temporal information in the AMASDA state site files database. We are also adding new information on novaculite projectile point distributions to the “Arkansas Novaculite” website (http://archeology.uark.edu/novaculite/index.html) database. Ultimately, the novaculite distribution map will be expanded to create maps for each time period. This attention to the station’s curated collections inventory has sparked several new projects. We inventoried over 10,000 artifacts from 1973 testing at the Spanish Diggings site (3GA48) in Garland County, the largest of the Ouachita Mountains novaculite quarries. Novaculite debris from this quarry can now be compared with excavated samples of chipping debris and in-process pieces from other quarries and habitation sites. Diagnostic dart points (Marshall and Gary, var. Gary) indicate use of the quarry at least during the Middle and Late Archaic and Early Woodland periods (ca. 6000-200 B.C.).

Preliminary Description

In northeastern Oklahoma, very little is known about the transition from the Late Archaic to the Woodland period (Wyckoff and Brooks, 1983: 55). To date, most of the archeological evidence documenting this time period has been derived from sites with mixed or otherwise uncertain components. In this report, we present a preliminary description of a small rockshelter, 34RO252, which has a Late Archaic deposit stratigraphically below a Woodland era cultural deposit. These two deposits are unmixed, discrete, and are physically separated by an apparently sterile clay soil horizon. It is anticipated that the stratified cultural deposits at this site will help characterize the transition from the Late Archaic to the Early Woodland period along the Verdigris River in northeast Oklahoma. This site was first reported in April 1994 by two men who had discovered partially exposed human skeletal remains located in the rear remnant of a rockshelter at Oologah Lake in Rogers County, Oklahoma. The two men illegally excavated the remains and removed them from the site. 1 The rockshelter where the remains originated was subsequently examined by the authors and additional skeletal material was identified, in situ, in an exposed soil profile. A series of three radiocarbon assays, described below, placed the cultural deposit and the human remains within the Late Archaic-Woodland period (circa 780 B.C. to A.O. 900).2 This site is provisionally classified as corresponding to a cultural sequence that includes the old Grove C described by Purrington and Vehik.

AbstractAcanmul is a medium-size center located at the north end of the Bay of Campeche about 25 km northeast of the city of Campeche. Between 1999 and 2005, three independent sets of investigations and major architectural consolidation were carried out at the center by archaeologists from the Universidad Autónoma de Campeche (UAC), the Instituto Nacional de Antropología e Historia (INAH), Centro Regional de Campeche, and UAC in collaboration with San Diego State University. These efforts produced a wealth of new information on the archaeology of the central Campeche coast, including new insights into the emergence and evolution of the northern slateware tradition and the architectural history of the central coast from Preclassic through Postclassic times. New data concerning changing relationships through time of the central coast Maya to both the interior central and southern lowlands and to the northern plains also were documented, as was the mid ninth century sacking of the center. This article synthesizes the findings of the three separate institutional efforts at Acanmul and offers a number of new cultural historical scenarios and hypotheses based on them.

This introduction to the edited volume by Brown and Bey summarizes past research on the Preclassic Maya and discusses an explosion of new information from the last fifteen years pushing back the origins of social complexity into the Middle Preclassic. This chapter highlights the fact that this volume brings together important archaeology and research considering the Middle and Late Preclassic periods from both the southern and northern Maya lowlands for the first time. The Late Preclassic was long thought to be the time period by which archaeologists could explain the rise and nature of Classic Maya culture. However, as the fifteen chapters in this volume argue, any discussion of the development of social complexity must be focused on the Middle Preclassic (1000-300 B.C.).

Metribuzin is a mobile pesticide widely used in agriculture and has great potential for soil migration. In addition, weather and soil conditions in the non-chernozem zone of Russia contribute to the movement of pesticides in the soil. The behaviour of metribuzin was studied in a lysimetric experiment. The experiment was carried out at the lysimeters of the Soil Research Station of Moscow State University from June 2016 to December 2017. Mertribuzin was applied in lysimeters in maximum recommended and eightfold rates two years in a row. Used in the recommended rate, metribuzin was detected in the samples of lysimetric water once at a concentration of 14 µg L-1 (6% of the samples analyzed). Applied in the eightfold rate, it was detected in 39.5% of samples, the maximum concentration was 180 µg L-1. The experiment revealed that metribuzin is able to leach bottom of the soil profile. The concentration of metribuzin found in the variant with the recommended rate is lower than the hygienic index adopted in Russian Federation for metribuzin, which indicates that the risk of metribuzin application for people is low.

Field experiments were conducted in 2006, 2007, and 2008 at the Louisiana State University Agricultural Center's Northeast Research Station near St. Joseph, LA, to evaluate imazosulfuron programs involving rate, application timings, and tank mixes for PRE and POST broadleaf weed control in drill-seeded rice. Imazosulfuron showed residual activity against both Texasweed and hemp sesbania. PRE-applied imazosulfuron at 168 g ai ha−1and higher rates provided 83 to 93% Texasweed control at 4 WAP. At 12 WAP, Texasweed control with 168 g ha−1and higher rates was 92%. Hemp sesbania control with 168 g ha−1and higher rates was 86 to 89% at 4 WAP and 65 to 86% at 12 WAP. Imazosulfuron at 224 g ha−1applied EPOST provided 84 to 93% Texasweed control and 82 to 87% hemp sesbania control, and it was as effective as its tank mixture with bispyribac-sodium. When applied LPOST, four- to five-leaf Texasweed, imazosulfuron alone at 224 g ha−1was not effective against Texasweed and hemp sesbania, but did improve weed control when mixed with bispyribac-sodium at 17.6 g ai ha−1.

Frequency Peak

Stamped or impressed designs on pottery from a group of relatively early sites in northern Georgia provide new data on the origin of several well known motifs of later times, and add to the evidence for a considerable cultural continuity between the archaeological phases of this area.In a previous article for american antiquity (Vol. XIV, pp. 201-9), I summarized the general ceramic sequence in the Etowah Drainage. Fabric impressed pottery seems to be the first majority ware in this area. It gradually decreased in popularity as Mossy Oak Simple Stamped increased and Deptford Bold and Linear Check Stamped appeared. The last named, together with Deptford Simple Stamped, became majority types during Late Archaic or Early Woodland times. In the meantime Woodstock Stamped and Woodstock Incised pottery appeared, but did not reach their frequency peak until Early Swift Creek had presumably degenerated into its later form near the end of the Middle Woodland period. Napier Stamped appeared at this time. Napier and Woodstock pottery strongly influenced the Early Mississippi "Etowah" wares, both stamped and incised. In the latter part of this period, Savannah Stamped intruded briefly, but the Etowah types persisted and finally deteriorated in carefulness of execution, thus evolving into the Lamar pottery of Late Mississippi time.

New Evidence

Fiber-tempered potsherds recovered from three sites of the Nebo Hill phase in western Missouri and eastern Kansas date to between 4550 and 3550 radiocarbon years (2600–1600 B.C.) and represent the earliest dated vessels in the midwest. The occurence of fiber-tempered pottery at this time period and this far north and west of the traditionally-defined southeastern hearth for such wares requires a major reappraisal of the assumed distribution and antiquity of Late Archaic ceramics in eastern North America. This report describes the ceramic sherds from the Nebo Hill type site in terms of their method of manufacture and probable use, and identifies factors influencing their survival and preservation in the middle-latitude lowlands. It is proposed that the temperate latitude distribution pattern of shallowly-buried, fiber-tempered potsherds is shaped primarily by the variables of time, ambient moisture and temperature, and ware porosity, and is not necessarily isomorphic with the prehistoric distribution of fiber-tempered vessels.
