1-14 (14 Records)
AZ T:12:397 (ASM) is a historic canal exposure uncovered on the north side of McDowell Road. Archaeological monitoring of the excavations for waterline improvement uncovered a historic canal (AZ T:12:397 [ASM]). The canal was minimally exposed and its National Register eligibility cannot be assessed at this time. No further archaeological work is recommended for this project. EcoPlan recommends, however, that if future ground disturbing projects are proposed in the vicinity of the canal,...
EXAMINATION OF ORGANIC RESIDUES, BASKETRY, AND BOTANIC REMAINS FROM AZTEC RUINS, NEW MEXICO (2009)
Four residue samples from rooms in the West Ruin at Aztec Ruins, New Mexico, were examined to identify the contents of the residue. Two of these residue samples were collected from baskets. As appropriate, analysis of the residue samples included macrofloral examination and/or microscopic identification of starches and phytoliths. A botanic sample from Kiva D and material from the foundation of a coiled basketry ladle also were submitted for identification.
EXAMINATION OF SEDIMENTS FROM B. F. SISK DAM, CENTRAL CALIFORNIA FOR POLLEN, PHYTOLITHS, AND DIATOMS TO IDENTIFY PROBABLE AGE OF THE DEPOSITS (2009)
Five sediment samples collected from B.F. Sisk Dam in central California, approximately 12 km west of Los Banos, were examined to recover pollen, phytoliths, and diatoms. These sediments were recovered from the downstream toe of the dam near the former junction of San Luis and Cottonwood Creeks. These samples are believed to represent the Plio-Pleistocene Tulare Formation and possibly the Corcoran Clay, one of the uppermost units within the Tulare. Analysis was conducted in an effort to verify...
FEASIBILITY STUDY OF POLLEN, DIATOM, AND MACROFLORAL ANALYSES AT HELLER LAKE, UTAH, WITH SUPPORTING ARCHAEOCLIMATE MODELS (2004)
The Heller Lake site is located within the Ashley National Forest near the headwaters of Dry Gulch Creek. The lake is located on the south slopes of the Uinta Range, between the Uintah and Ouray Indian reservation and the High Uintas wilderness, at an elevation of 9400'. The sampling site is located in an alpine moraine plant community within the western montane biome. A mosiac of other plant communities are located in the general site area with differences based upon substrate and slope....
POLLEN AND DIATOM ANALYSIS FOR OFF-SITE TRENCHES AT FB 16004, FB 16006, AND FB 16008, FORT BLISS, NEW MEXICO (2009)
Four trenches were cut through a low lying playa surrounded by large eolian dune piles and sand sheets in the Tularosa Basin of New Mexico. Six sediment samples from three of the trenches (Geological Trench 1 and 2 and FB 16008) were submitted for pollen and diatom analysis.
POLLEN AND DIATOM ANALYSIS OF SEDIMENTS FROM METAMORPHOSE POINT (SITE BHT 8 and BHT 4; PROJECT NO. 560-033), FORT BLISS, NEW MEXICO (2008)
A total of seven pollen samples and one sample for diatom analysis were submitted from Metamorphose Point (Site BHT 8). These samples were collected from two different sections of a trench cut. Two sections were sampled at the site. Section 1 included a paleosol (2Ab) that was sampled at the bottom, middle, and top for pollen analysis to better understand the local paleoenvironment. Section 2 is represented by pollen samples from the bottom, middle, and top of possible playa deposits. In...
POLLEN, DIATOM, AND MACROFLORAL ANALYSIS OF SAMPLES FROM A CORE NEAR CROSS PLAINS, WISCONSIN (2011)
Six samples representing marsh, lacustrine, and outwash sediment deposits were removed from a core that was collected from a small tributary flowing south into Black Earth Creek just outside the town of Cross Plains, Wisconsin for the purpose of recovering pollen, diatoms, and macrofloral remains. Analysis of these samples was undertaken as a pilot study to examine preservation and the potential for recovering information about vegetation and the paleoenvironmental history of this area from...
POLLEN, DIATOM, AND MACROFLORAL ANALYSIS OF SAMPLES FROM A CORE NEAR MAZOMANIE, WISCONSIN (2011)
Four samples from a core collected in marsh, lacustrine, and outwash sediment immediately outboard of the Last Glacial Maximum ice margin were examined for pollen, diatoms, and macrofloral remains. The core location is in south-central Wisconsin near the town of Mazomanie. The samples were widely spaced through deposits between 44 and 25 feet in depth.
POLLEN, MACROFLORAL, AND DIATOM ANALYSIS FROM PIPE SPRING NATIONAL MONUMENT, ARIZONA (2001)
Two sediment samples collected from a black, organic layer exposed in a trench at Pipe Spring National Monument, Arizona, were examined for pollen, diatoms, and/or macrofloral remains. This layer is believed to represent an intact, natural organic stratum that formed when water ponded at the mouth of the spring. Pollen, macrofloral, and diatom analyses will be used to define environmental information and local vegetation at the time this stratum was deposited. Pollen analysis provides evidence...
POLLEN, MACROFLORAL, AND DIATOM ANALYSIS, AND AMS RADIOCARBON DATING OF A CORE; AND PROTEIN RESIDUE ANALYSIS OF LITHIC ARTIFACTS FROM THE BEAR CREEK SITE (45KI839), KING COUNTY, WASHINGTON (2014)
The Bear Creek site (45KI839), a multicomponent Paleoindian site, is situated on the northern bank of the lower reach of Bear Creek in King County, Washington. A core was extracted from undisturbed sediments in the eastern portion of the site using a three-inch diameter, beveled section of ABS tube that was pushed through Strata II, Va, Vb, Vc, and VI. Multiple analyses, including pollen, macrofloral, and diatom, of the core sediments were undertaken to provide information about the...
POLLEN, PARASITE, PHYTOLITH, STARCH, MACROFLORAL AND DIATOM ANALYSIS OF SOIL SAMPLES FROM A TRANSBAY BURIAL, SAN FRANCISCO, CALIFORNIA (2014)
The Transbay Project encompasses large portions of San Francisco’s South of Market neighborhood on the western side of San Francisco Bay. Near the bottom excavation elevation, at the interface of Marine Sands with Lower Bay Mud, an individual burial was excavated. The burial included human remains and a woven mat that lined the pit and was folded over the top of the individual’s legs (Aimee Arrigoni, personal communication April 17, 2014). From this burial four soil samples were submitted for...
POLLEN, PHYTOLITH, AND DIATOM ANALYSIS OF THREE SAMPLES FROM THE DEVIL’S LAKE GORGE CORE, WISCONSIN (2012)
Three sediment samples were selected for preliminary pollen, phytolith, and diatom analysis from a 885 cm-deep core collected from glacial maximum-age sediments deposited in Devil’s Lake in the Baraboo Hills of south-central Wisconsin. This analysis was designed to assess the quality of the proxy data before the continuation of analyses of additional samples. Upon completion of this analysis and based on recovery of significant quantities of microscopic charcoal in the pollen samples, four...
POLLEN, STARCH, PHYTOLlTH, AND PROTEIN RESIDUE ANALYSIS OF ARTIFACTS AND SOIL SAMPLES FROM MIDDEN DEPOSITS AT SITES CA-ORA-263 AND CA-ORA-264; POLLEN, PHYTOLlTH, AND DIATOM ANALYSIS OF CORE SAMPLES FROM AN OFF-SITE LOCATION; AND ARCHAEOCLATIC MODELING FOR THE HELLMAN RANCH PROJECT, CALIFORNIA (2004)
Pollen, phytolith, starch, and protein residue analyses were conducted on artifacts recovered in association with burials at site CA-ORA-263 in southern California, as well as on the soil control samples associated with these artifacts collected from midden sediments. An isolated basin metate at site CA-ORA-264 and a soil control from the basin fill also were examined for pollen, starches, phytoliths, and possible protein residues. These analyses were undertaken to be able to more fully...
STRATIGRAPHIC POLLEN, PHYTOLITH, AND DIATOM ANALYSIS OF SAMPLES FROM THE MAMMOTH SITE (41BX1239), TEXAS (2011)
Sample were collected stratigraphically from the west wall of Backhoe Trench 7 at the Mammoth Site (41BX1239) in Bexar County, Texas. These samples were originally designated for diatom and/or phytolith analysis. Upon review of soil conditions at the site, pollen analysis was recommended as the first priority. Due to high sediment pH, diatom and phytolith dissolution was identified as a potential problem. Analysis proceeded on these sediments for the recovery and identification of pollen,...
