Applying Simple Magnetic Depth Estimation Techniques to Archaeo-geophysics (2019)
DOCUMENT Citation Only Jeremy Menzer.

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Magnetometry is probably the most widely used archaeo-geophysical technique in the world, despite its major drawback of an absence of depth information to an anomalous source. Many users, novices in particular, are under the impression that magnetometry does not or cannot provide depth information. Yet, depth estimation techniques are commonly utilized in...


Archeological Investigations Along the Salt-Gila Aqueduct (1979)
DOCUMENT Full-Text Pat H. Stein.

In 1978, the Bureau of Reclamation (Reclamation) directed the Museum of Northern Arizona (MNA) to complete an intensive archaeological survey of the proposed alignment for the Salt-Gila Aqueduct, a feature of the Central Arizona Project. The survey area was 11,115 acres and included the 60 mile-long transmission line (with a typical width of 200 meters), three proposed utility line locations, one flood retention dike location, 11 possible spoil or realignment areas, and a subsidence well....

Dolores Archaeological Program Technical Reports, DAP-078: Study of Correlation Between Magnetic Reconnaissance and Excavation in the Dolores Archaeological Program (1983)
DOCUMENT Full-Text Patricia K. Burns. Robert Huggins. John W. Weymouth.

In September of 1978, a magnetic reconnaissance program was initiated within the Bureau of Reclamation Dolores Project area of Colorado for the DAP (Dolores Archaeological Program). Themagnetic program was continued throughout the 1979 field season, by which time 26 grids, at 25 selected prehistoric sites, had been magnetically surveyed. The raw data obtained by these surveys was sent to NEBCAR (Nebraska Center for Archaeophysical Research) to be analyzed by Rob Huggins under the direction of...


Dolores Archaeological Program Technical Reports, DAP-108: Excavations at Windy Wheat Hamlet (Site 5MT4644), a Pueblo I habitation (1984)
DOCUMENT Full-Text Joel M. Brisbin.

Windy Wheat Hamlet (Site 5MT4644) is a Pueblo I habitation site located in the Sagehen Flats Locality of the Dolores Archaeological Program study area. Three elements of occupation, occurring between A.D. 740 and the early 800's, have been recognized at Windy Wheat Hamlet. During the earliest element, which dates to the late Sagehill Subphase, one pitstructure was occupied at the site. No surface rooms were found to be associated with this element, but extensive pl owing may have destroyed...


The Fort St. Joseph Archaeological Project
PROJECT Michael Nassaney.

The Fort St. Joseph Archaeological Project is a collaboration between Western Michigan University and the City of Niles, MI to investigate, interpret, and preserve the physical remains of the site of Fort St. Joseph, a mission, garrison, and trading post complex occupied from 1691 to 1781 by the French then British. Since its inception, the Project has cultivated a robust program of public archaeology to involve and invest the community in the preservation of the site and more generally, the...


Geomagnetic Storms are a Problem in the Gulf of Mexico, Too… (2017)
DOCUMENT Citation Only Brandi Carrier. Michael Heinz.

At SHA 2016, evidence was presented, and subsequently published, demonstrating that strong magnetic field perturbations resulting from Earth-directed solar events can adversely affect marine archaeological survey. Survey and observatory magnetometer data from mid-latitude regions confirmed the immediate onset of geomagnetic storms and the fast compression of the magnetopause, creating a short-duration, high amplitude spike in Earth’s magnetic field that appears similar to the signature of an...


Geophysical Methods at the Hollister Site: Summary of Finds (2018)
DOCUMENT Citation Only Peter Leach. Maeve Herrick. Jasmine Saxon.

Geophysical methods in archaeology are increasingly integrated into traditional archaeological surveys. Remote sensing is valuable because it allows for large areas to be surveyed relatively quickly and noninvasively. At the Hollister site in South Glastonbury, Connecticut, magnetometry and ground-penetrating radar, were implemented over a 140x140 meter area. Magnetometry measures alterations to earth’s magnetic field. This method is helpful for identifying a number of artifacts and features,...


A Geophysical Survey of Fort St. Joseph (20BE23), Niles, Michigan (2008)
DOCUMENT Full-Text Daniel Lynch.

Fort St. Joseph is a 17th-18th century French (and later English) mission-garrison-trading post complex located in southwest Michigan. A geophysical survey was performed and the results of the survey were tested through archaeological excavation. The geophysical methods included ground penetrating radar, electromagnetic induction, electrical resistivity, magnetic gradiometry, and magnetic susceptibility. The results of the archaeological excavations demonstrate that magnetic gradiometry was the...

Moving up in the World: Comparing Magnetic Gradiometer Survey Results from Monumental Sites Using Small, Medium, and Large Magnetometer Systems (2019)
DOCUMENT Citation Only Jarrod Burks.

This is an abstract from the "Monumental Surveys: New Insights from Landscape-Scale Geophysics" session, at the 84th annual meeting of the Society for American Archaeology. The problem with monumental earthwork sites in Ohio is that they are, well, monumental in scale! These large sites, many topping 50 ha in area, are a major challenge for geophysical surveys because they simply require too much time to completely survey. However, recent advances in instrumentation and computers is making it...


Near-Surface Geophysical Investigations at the Multicomponent Magnolia Valley Site (40RD314) in Rutherford County, Tennessee (2015)
DOCUMENT Citation Only Timothy De Smet. Tanya M. Peres. Jesse W. Tune.

In May 2014 we collected magnetic gradiometry, frequency-domain electromagnetic-induction (EMI), and ground-penetrating radar (GPR) data at the Magnolia Valley site (40RD314) in Rutherford County, Tennessee with the Middle Tennessee State University 2014 Field School, a component of the MTSU Rutherford County Archaeology Research Project (RCARP). We collected data using Geometrics G-858 cesium vapor magnetometer, GSSI’s Profiler EMP-400 multifrequency electromagnetic conductivity meter, and...


Recognizing Geomagnetic Storms in Marine Magnetometer Data: Toward Improved Archaeological Resource Identification Practices (2016)
DOCUMENT Citation Only Brandi Carrier. Antti Pulkkinen. Michael Heinz.

Strong magnetic field perturbations resulting from Earth-directed solar events can adversely affect marine archaeological survey. The immediate onset of geomagnetic storms and fast compression of the magnetopause create short duration, high amplitude spikes in Earth’s magnetic field that appear similar to signatures of archaeological anomalies. Aggressive processing, analysis, and comparison of single instrument survey and observatory datasets collected during geomagnetic storms prevented...


Remote Sensing at 45PO435, the South Flying Goose Site (2017)
DOCUMENT Citation Only John T Dorwin.

In the summer of 2014, during the course of National Register evaluation of 45PO435, a site on the Kalispel Indian Reservation along the Pend Oreille River in the mountains of eastern Washington, an isolated small burned structure was located by means of magnetometry and ground penetrating radar. Its existence was confirmed by means of soil augering. Its dimensions were delineated by a combination of augering, excavation and electrical resistance. This paper discusses the contributions made by...


What Could Possibly Go Wrong… Small Craft in Search of a Manila Galleon (2017)
DOCUMENT Citation Only Jack G Hunter. Brooke Basse.

The Baja California Manila Galleon shipwreck site location was established from analysis of onshore artifact distribution.  Increasing attempts have been made to investigate the offshore source of this material by utilizing magnetometry and the excavation of detected anomalies.  The magnetometer surveys went well and buried iron associated with the wreck site were buoyed and mapped.  However, investigation of the buried anomalies proved to be more difficult than anticipated, as they were found...
