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.

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.
