Maps of individual colonies were compiled using the most accurate and recent information. They consulted published maps in combination with data from surveys of local geographical features, such as roads, rivers, or landholdings. This property survey by George Washington at age 18 is one example of these maps. This map is one of approximately 75 surviving surveys of the 199 that Washington completed during his career as a county surveyor. This survey documents 316 acres between the north and south branches of Bullskin Run, which is located in present-day Jefferson County, West Virginia.
