Archeology is the multi-faceted study of human history and culture through artifacts and other physical remains. Archeologists may specialize in many different subfields that fall into 3 categories: 

• Prehistoric Archeology focuses on understanding the people who predate written history.
• Historic Archeology is the study of people and cultures through artifacts which are 50 years or older.
• Classical Archeology combines prehistoric and historic methods to uncover ancient monuments and historical events. 

Archeologists often work to conduct surveys, plan development projects, and mitigate damages to historical sites. Beginning in the 1940’s all archeological sites found in the United States have been kept on record in a large database. Most archeologists employed today are working to ensure compliance with the Cultural Resource Management (CRM) protocols, and antiquities laws on all private and government construction or reclamation projects.
