The Northwest Chapter of the Iowa Archeological Society (NWIAS) was organized as a branch of the Iowa Archeological Society, and members are pledged to support and further the aims and purposes of the parent organization.
Goals Our goals are to further archaeological knowledge and to gather, record, and publish information of all archaeological remains, whether they are sites, data, or artifacts, for the benefit of future generations of Iowans and scientists.
Meetings and Events The Northwest Chapter meets on the first Wednesday of every month at 6 p.m. In addition to discussing upcoming events, these monthly meetings feature special activities, field trips, or presentations. These meetings are open to the public, so feel free to bring a friend!
Feel free to email firstname.lastname@example.org with any questions!
How Geophysical Surveys can meet your Needs Archaeologists can use geophysical surveys as a non-invasive technique to identify buried archaeological resources prior to or without excavation. Buried materials or features often produce a slight different magnetic field than the local magnetic field around them. A gradiometer is a geophysical survey tool that measures these local magnetic fields and anomalies. This technique not only saves time and money, it also helps preserve our important cultural resources for the future.Examples of Gradiometer Applications• Prehistoric Camp Sites• Prehistoric Villages• Prehistoric Earthworks and Mounds• Historic Graves and Cemeteries• Historic Farmsteads• Other Historic Settings
About our System The Sanford Museum uses the FM256 fluxgate gradiometer in combination with Geoplot software, ArcGIS, total station, and GPS mapping equipment in order to create three-dimensional maps. These maps can demonstrate potential feature locations, densities, and landscape of archaeological sites without ever breaking ground. The data collected with these instruments will be in digital format, leading to fast, efficient and accurate information.
