Explanation of Search Fields
The search engine used on this database is quite flexible and forgiving. It is not case sensitive. If you are looking for all dates associated with a particular lab, you can simply enter Beta into the Lab # field. If you are looking for Beta lab dates between 2000 and 3000 years BP, enter Beta into the Lab # field, 3000 into the Younger than field, and 2000 into the Older than field. Dates do not require a comma.

Region or Borden Block: The upper case letters in the Borden designation (only for sites in Canada). For the contiguous United States, NW retrieves data from Washington, Oregon, Idaho and sites west of the continental divide in Montana and Wyoming; NC retrieves data from Iowa, Minnesota, Nebraska, North Dakota, South Dakota, and sites east of the continental divide in Montana and Wyoming; MW retrieves data from Illinois, Indiana, Kentucky, Michigan, Ohio, West Virginia, and Wisconsin; and NE retrieves data from the New England states plus Delaware, Maryland, New Jersey, New York, and Pennsylvania.return to top of page
Site Code or Borden Number: For Canada, the site designation in the Borden system, reflects latitude and longitude in blocks of 10-20 minutes. Palaeobiological sites lacking such designations are given the suffix "VP". Alaskan site codes begin "AK" followed by a 3-letter designation for the 1:250,000 quadrangle sheet, and a sequence number. Most of the contiguous states use site codes that designate location by county (the Smithsonian System). return to top of page
