Aerial Reconnaissance - The technique of searching for sites and features, both cultural and natural, from the air, often using aerial photography or the human eye.Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.This method is useful for archaeologists working in areas where volcanic eruptions have left layers of ash above and below an archaeological deposit.The volcanic layers can be dated, and the archaeological material will date to the period between those two volcanic eruptions.

In relative dating, the temporal order of a sequence of events is determined, allowing the investigator to surmise whether a particular object or event is older or younger than, or occurred before or after, another object or event. - "Abbreviation for the term Anno Domini Nostri Jesu Christi (or simply Anno Domini) which means ""in the year of our Lord Jesus Christ."" Years are counted from the traditionally recognized year of the birth of Jesus. E.)." Absolute Dating - Collective term for techniques that assign specific dates or date ranges, in calendar years, to artifacts and other archaeological finds.It was characterized by large bifaces, particularly hand axes.Relative dating methods do not tell archaeologists exactly how old things are, but only how old things are relative to each other.Archaeologists work on the principle that objects at the bottom of an undisturbed were put there before objects that are above them, so objects found in the lower levels of a site are usually older than objects found in higher levels.
