It is also the site of a significant Late Woodland period settlement known as the Walker Prehistoric Village, which was added to the National Register of Historic Places in 1975.In 2002, following the diagnosis of two Loudoun County teenagers with malaria, mosquitoes from the island were found to carry the Plasmodium vivax malarial parasite.In 2004, Selden Island was purchased by the Howard Hughes Medical Institute as an addition to the Janelia Farm Research Campus.

Mt. Nebo is a historic home located at Poolesville, Montgomery County, Maryland, United States. It is a large 2+1⁄2-story gable-roofed frame dwelling constructed in three periods: the main block, dating to the second quarter of the 19th century; a 1+1⁄2-story wing extends from the rear of the main block, which appears to have been an earlier dwelling from the late 18th century; and a two-story addition was made to the east gable end of the main block around the turn of the 20th century. Also on the property is a mid-19th-century log smokehouse and the remains of an early terraced "waterfall" garden.
