In May 2007, Thomas Kutys, an archaeologist with A.D. Marble & Company, a Cultural Resource Management firm based in Conshohocken, Pennsylvania, discovered a stone and brick drain on the Fort Duquesne site. It is thought to have drained one of the fort's many buildings. Due to its depth in the ground, this drain may be all of the fort that has survived. The entire northern half of the former fort site was disrupted and destroyed by the heavy industrial development of the area during the 19th century.
