In both sites, Middle Paleolithic contexts were previously dated by radiocarbon to less than 42 ka cal BP.

Uncharred wood can also survive in caves, arid areas, and water-logged areas.

The hearth, as a locus of food preparation may also offer other datable materials such as bone or maize cobs.

The magnetic enhancement of burned features makes it possible to map and target them as sources of datable carbon.

The Eagle Tree site (48CO2920) in northeastern Wyoming offers an example of the use of magnetic survey for targeting datable features.

Eagle Tree was a spatially extensive prehistoric campsite with a very sparse distribution of features and artifacts.

Among the dating methods that require or can be performed on burned or thermally-altered materials are: May generally be considered the most useful and cost-effective physical dating method for archaeological investigation.

The preservation advantage of charcoal over unburned wood makes it a common source of datable carbon.Separation and identification of charcoal for radiocarbon analysis is currently being used in several other fields of study, including paleoflood studies, paleoseismology, and paleoclimatology.Charcoal and other charred organic remains that have been identified prior to submission for radiocarbon dating are the best materials to date, and are far superior to bulk soil samples (See POSTED PAPERS for Charcoal or wood samples can be collected directly from a soil or cultural context and submitted for identification.At archaeological sites, identification of charcoal and wood can provide information concerning trees and shrubs growing at or near a particular site, as well as types of wood burned as fuel or used as building materials.Charcoal also is commonly submitted for radiocarbon analysis. The latter is most likely produced by anatomically modern humans.
