Tree-Ring Dating and Historic Structures: A Look at the Science of Dendrochronology
On November 21 at 7 p.m. in the Visitor Center Auditorium of Historic St. Mary’s City, dendrochronologist Michael Worthington will give a free, public lecture titled “Tree Ring Dating and Historic Structures: A Look at the Science of Dendrochronology.”
The science of dendrochronology or tree-ring dating has long been used to provide insight into many of America’s most famous buildings, from George Washington’s Mount Vernon to James Madison’s Montpelier, the birthplaces of John Adams and John Quincy Adams, and much of the town of Colonial Williamsburg.
But did you know that pioneering work on its development was done right here in St. Mary’s City? Join dendrochronologist Michael Worthington on an exploration of this fascinating but little-known science and the ways that it has changed our understanding of historic structures. He will discuss how dendrochronology works, how it has been applied in England and America, and the ways that it has shed light on the architectural development of Maryland and beyond.
The evening lecture will be held inside the Visitor Center Auditorium, 18751 Hogaboom Lane, St. Mary’s City, MD 20686. This lecture will be free and open to the public.
Historic St. Mary’s City is a museum of living history and archaeology on the site of Maryland’s first capital in beautiful, tidewater Southern Maryland.

About Michael Worthington:
Michael Worthington is a dendrochronologist with wide-ranging experience working on both sides of the Atlantic. Among the many buildings he has dated are the Josiah Henson Site (Uncle Tom’s Cabin) and Doughoregan Manor in Maryland; Decatur House in Washington DC; Mount Vernon and many of the buildings in Colonial Williamsburg in Virginia; Drayton Hall in South Carolina; the birthplaces of John Adams and John Quincy Adams and the Fairbanks House (the oldest surviving timber frame house in North America) in Massachusetts; the Officers’ Club at the Presidio in San Francisco, California; and Windsor Castle, Westminster Abbey, and the Tower of London in England.
He also enjoys working on smaller vernacular buildings and has been commissioned by numerous homeowners in the US and Europe to date their houses privately. He has extensive media experience and has appeared on the PBS television series “History Detectives” and “Time Team America.”
Michael began his career in buildings as an industrial archaeologist at the Ironbridge Gorge Museum in Shropshire, England.
He spent seven years as the excavation supervisor for the British television series “Time Team.” After deciding to specialize in dendrochronology, he received his academic training through a grant from English Heritage at the University of Oxford. At Oxford, he was a member of staff at the Research Laboratory for Archaeology and the History of Art and an assistant tutor on the master’s degree course in Archaeological Science.
Upon moving full-time to the United States in 2010, Michael opened the Oxford Tree-Ring Laboratory. He currently resides in Baltimore, Maryland.
The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.
To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at email@example.com
Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
