Waysons Corner, Maryland

The Nanjemoy Formation is a geologic formation pertaining to both the Wilcox Group and the Pamunkey Group of the eastern United States, stretching across the states of Virginia, Maryland, and District of Columbia. The formation crops out east of the Appalachians and dates back to the Paleogene period. Specifically to the Ypresian stage of the Eocene epoch, about 55 to 50 Ma or Wasatchian in the NALMA classification, defined by the contemporaneous Wasatch Formation of the Pacific US coast. The about 20 metres (66 ft) thin formation crops out in a narrow irregular band and only in certain of the many creeks of the Maryland peninsula and on the southern side of the Potomac River in Virginia. The two members the formation was divided into by Clark and Martin in 1901; Potapaco and Woodstock, represent different phases in the basin history. The lower Potapaco Member is much more clayey, described as marl, than the upper Woodstock Member, probably characteristic of less storm influences in the shallow shelf sediments. The formation has provided a wealth of fossils of mainly fish, but also mammals, reptiles, birds and flora. The presence of the sharks Otodus obliquus and Carcharocles aksuaticus, as well as various other shark and ray species are notable. Crocodylian, snake, turtle, mammal, and bird remains have all been found in the Nanjemoy Formation.

Compton Bassett is a historic home in Upper Marlboro, Prince George's County, Maryland, United States, that was constructed ca. 1783.

Also on the property is a family burial ground.The Hill family and descendants lived at the premise from 1699 to 1900. Hills Bridge (700 meters to the southeast) has carried traffic over the Patuxent River here since a toll bridge was first constructed in 1852 by W.B. Hill. Compton Bassett was listed on the National Register of Historic Places in 1983. In July 2010 the house and grounds were acquired by the Maryland-National Capital Park and Planning Commission. In an effort to slow-down the effects of time, in 2018 the house underwent a significant structural stabilization. MNCCPC engaged the nationally recognized restoration firm The Durable Restoration Company, working with a local firm to design and build the structural framework system to reinforce the external and internal portions of the house.

Mount Pleasant is 2+1⁄2-story brick structure with a gambrel roof and is about two-thirds its original length. It is located near Upper Marlboro in Prince George's County, Maryland. Mount Pleasant was patented in 1697 to Richard Marsham, whose wife Anne was the daughter of Leonard Calvert, Governor of Maryland. Their grandson, Marsham Waring, inherited the home from his grandfather in 1713. His son, Richard Marsham Waring had a son, Richard Marsham Jr., born in 1733, who then inherited Mount Pleasant and Patented and Certified the tract of land dubbed "Mount Pleasant Enlarged" in 1760. On August 21, 1764, Richard Marsham Jr. sold the 451+3⁄4 acre tract of land to his brother John for £474.6s.9d. John later built the standing house in the years between 1764 and 1785 (conflicting dates). John died in 1813 and was buried at Mount Pleasant.Mount Pleasant is an example of an almost distinctively Maryland style of house—the English gambrel roof dwelling in brick, with the steep gambrel which has dormers almost flush with the second pitch of the roof. This house is significant primarily for its architecture and as a representative example of a more modest type of mid-Georgian dwelling than others in Maryland such as Montpelier, and probably a closer reflection of the architectural ancestry than the Palladian country house. As a more modest dwelling Mount Pleasant is an unusual survivor.Thomas Fielder Bowie is interred in the Waring family burial ground on this site.

The PGSO was involved with events that occurred during the burning of Washington and affected the writing of "The Star-Spangled Banner". Prior to 1931, the PGSO was the sole law enforcement organization of the county.Today, the duties of the sheriff include law enforcement services of the two county courthouses and surrounding property, service of court-ordered warrants, writs, protective orders, and other injunctions, and limited patrol responsibility with the County Police.

The creation of the School Resource Deputy division has placed a deputy sheriff at all of the local high schools, replacing the County Police. All other law enforcement services of the county are provided by multiple agencies but mostly left to the separate Prince George's County Police Department (PGPD), though some responsibilities are shared by both agencies. The PGSO, like most other county-level law enforcement agencies in the United States, is a progressive agency with an array of services, from the Specialized Services Team (dealing with high-risk arrest warrants and barricaded situations) to community services aiding the county's residents in safety education. The PGSO was accredited for the first time by the Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA) in 2018.
