While your humble editor was away last week on vacation, archaeologists from John Milner Associates (JMA) remained hard at work excavating the site where the Museum of the American Revolution will be built. Today, lead archaeologist Rebecca Yamin recaps her team’s past two weeks of work:
Lots of progress over the past two weeks. Continuing excavations have revealed more features, mostly foundation walls and floors. JMA archaeologists followed contractor DeAngelo’s huge excavator, testing one shaft feature and documenting the remains of at least three structures. Close behind the archaeologists a drill was used to place supports for the shoring of the site.
The location and the construction methods of the structural remains will be used as an aid in determining the names of the people or businesses that once occupied them. We are comparing the location of foundation walls to Anna Coxe Toogood’s 1787 map reconstruction of the block and to later insurance maps.
The next stage of the work is to see what fragments of the 18th century remain under the basement floors of the buildings that were taken down when the Visitor’s Center was built on the site in 1975. Two floors—one brick and one concrete—belonging to buildings that once faced Third Street were lifted last week. Nothing was found beneath them, but the back of the lots they once covered had been heavily disturbed by the bell tower for the Visitor’s Center. The contractor is still struggling to remove its remains.
Pictured above is DeAngelo’s excavator and the map being used to help determine what once occupied the newly uncovered structures. (Thanks to Independence National Historical Park for supplying the map!)
Have questions for Dr. Yamin and her team? She’ll be available to talk about their work every Thursday between 10am-2pm on the steps of the First Bank of the United States across the street from the construction site. Or submit your questions to editor@amrevmuseum.org and we’ll answer them in a future post.
