The Greenwood gold mine operated in Prince William County, Virginia, United States, near the town of Independent Hill for a few years before closing in 1885. It was one of two known gold mines in Prince William County, the other being the Crawford placer prospect on Neabsco Creek, near I-95, though small amounts of gold were occasionally found at the Cabin Branch Pyrite Mine in nearby Dumfries. The Greenwood site was situated at the head of the North branch of Quantico Creek on what is now part of Prince William Forest Park near the intersection of Aden and Bristow Roads in the far northwestern area of the park. The site is situated along the Virginia Gold-Pyrite belt, which runs from northeast to southwest primarily through the counties of Fairfax, Prince William, Stafford, Spotsylvania, Buckingham, Culpeper, Cumberland, Fauquier, Floyd, Fluvanna, Goochland, Halifax, Louisa, Orange, and Patrick. Mining operations consisted of at least one shaft, a stamp mill, and some form of mercury amalgamation recovery. The mine was a significant source of mercury pollution on Quantico Creek, and has since undergone complete reclamation including the sealing of mine shaft(s), soil removal and/or decontamination, and removal of obvious tailings. The area of the former mine is also monitored by an array of groundwater wells, which are maintained by the NPS. The USGS maintains two active monitoring wells downstream of the mine site on the South Fork of the Quantico Creek. As of 2010, the only visible evidence of the mine are a few depressions in the soil. Engineered drainage structures from the reclamation efforts are visible. No intact structures or equipment remain. The National Park Service charges a fee for entry into the park and does not allow collecting of rocks or minerals.

The FBI Academy is the Federal Bureau of Investigation's law enforcement training and research center near the town of Quantico in Prince William County, Virginia. Operated by the bureau's Training Division, it was first opened for use on May 7, 1972, on 385 acres (156 ha) of woodland, which is not available for public tours. The academy was opened for the purpose of training the new agents after FBI agents were granted the power to arrest, and to possess a firearm, in 1933. As the newly armed agents needed somewhere to train, the Marine Corps granted them access to their firing ranges in Quantico, Virginia. After outgrowing the Marine Corps firing ranges the FBI was granted permission to build their own firing range and classroom on the base. Over time they added new sections such as a whole new wing, kitchen, and basement. But with the rapid growth it still was not enough for their needs. In 1965, the FBI received approval for a new complex at Quantico and construction began in 1969. The new facility opened in 1972, with more than two dozen classrooms, eight conference rooms, a large auditorium, a gym, pool, library, and a new firing range. The new complex had everything the FBI needed to train new agents in large numbers. In addition to training new FBI agents at the facility, the Training Division also instructs special agents, intelligence analysts, law enforcement officers, Drug Enforcement Administration agents, and foreign partners. The academy provides several training programs, including Firearms, Hogan's Alley (a training complex simulating a small town), Tactical and Emergency Vehicle Operations Center (TEVOC), Survival Skills, and Law Enforcement Executive Development. To meet the needs of these training programs the FBI has a 1.1-mile-long oval road track with a precision obstacle for conducting TEVOC. Hogan's Alley is a town that the FBI had built with the help of Hollywood set designers in order to give realistic training to agents. It helps the agents experience realistic and stressful scenarios to better prepare them for real-life situations.The academy occupies 547 acres (221 ha) on the US Marine Corps Base Quantico. It is located 36 miles outside Washington, D.C., and is a full service national training facility. In order to be able to attend the academy and become an FBI agent, a candidate must be aged between 23 and 37, a citizen of the United States, and possess a minimum of a bachelor's degree.

The FBI National Academy is a program of the FBI Academy for active U.S. law enforcement personnel and also for international law enforcement personnel who seek to enhance their credentials in their field and to raise law enforcement standards, knowledge, and also cooperation worldwide. The FBI National Academy is held four times a year, when up to 250 candidates go through a 10-week course.
