Bryan Haley uses ground penetrating radar to reveal features underground without digging. These samples are marked for true north at the time of collection. Data from this feature is compared to the regional secular variation curve in order to determine the best-fit date range for the feature's last firing event. Mystery of the Cooper Skull.

Ian Thompson demonstrates flintknapping and explains why it's an indigenous art form. We asked each member of Time Team America three important questions about archaeology. Within these weaker areas the local directions and intensities change gradually secular variation.
Eric Blinman, director of the New Mexico Office of Archaeological Studies, explains how archaeomagnetic dating can help archaeologists determine the age of their site.
Learn how ancient technology called an Atlatl gave Paleoindians a better shot at survival.
This involves sufficient mass to take samples from, and a suitable material with adequate magnetite to hold the remnant magnetism.
The magnetic declination at any given time can be frozen into a clay formation that contains magnetite and is heated above the Curie point.
Report a Problem Closed Captioning. Adrien Hannus describes Folsom people's hunting strategy and the innovation of the Atlatl. The weaker variations are the Earth's magnetic map. Concepts Deep time Geological history of Earth Geological time units.

Additional data points from archaeomagnetic samples with corresponding dating techniques such as tree ring dating or carbon dates, help refine the regional curves. The Archaeomagnetic Laboratory at the Illinois State Museum has secular variation curves for the southwest, mid-continent and southeast United States. Archaeomagnetic dating requires an undisturbed feature that has a high likelihood of containing a remnant magnetic moment from the last time it had passed through the Curie point.
