The Clement Oak is a large old white oak tree in Deptford, New Jersey. It is believed to have sprouted between 1555 and 1615. The Clement Oak is located behind the Deptford Wal-Mart, near Big Timber Creek, on land that once belonged to the Clement family. The original plans for construction of the Wal-Mart called for the tree to be felled, but Wal-Mart was persuaded to alter their plan so the tree could be spared. The girth of the tree at is. The estimated height is with an overall spread of over. The Clement Oak is said to have been known to the aboriginal Lenape, and to have been noticed by the first European settlers, as it served as a reference point in early land surveys. According to unsubstantiated local lore, native pow wows were held there, and a treaty between settlers and the Lenape was signed beneath its branches. The Gloucester CountyHistorical Society honored the Clement Oak during New Jersey's 300 year anniversary celebration in 1964. The Clement Oak was the site of the landing of the first aerial flight in the New World, a 1793 balloon flight. On January 9, 1793, Jean-Pierre Blanchard took off from Philadelphia and landed in Deptford at the Clement Oak. During his flight, Blanchard may have carried a personal letter from George Washington to be delivered to the owner of whatever property Blanchard happened to land on, which if true would have made the flight the first delivery of air mail in the United States as well; the letter is also said to have included a directive that all U.S. citizens were requested to assist him to return to Philadelphia, which if true would make it the first known use of a blood chit for an airman. A plaque at the tree commemorates the balloon flight. A second plaque commemorates the tree itself, which reads "The Clement Oak, which sheltered Lenape hunters 4 centuries ago and children at play in later years, is dedicated during the tercentenary of New Jersey as symbolic of the state's continuing growth – Gloucester County Historical Society July 1964". As of June 4, 2020 the entire top half of the Clement Oak has been torn away, leaving only a few green limbs.
