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. John Wah loves getting his hands dirty. Get a glimpse inside the largest known pit house on the Dillard site years ago. Adrien Hannus describes Folsom people's hunting strategy and the innovation of the Atlatl.

Eric Blinman, director of the New Mexico Office of Archaeological Studies, explains how archaeomagnetic dating can help archaeologists determine the age of their site. 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. The Archaeomagnetic Laboratory at the Illinois State Museum has secular variation curves for the southwest, mid-continent and southeast United States.

Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy. 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.
