It is on the west side of the river next to Marine Corps Base Quantico about 30 miles south of Washington.
Once known as Scott's Island, little is known about its history prior to the 1900s due to Stafford County's records being burned in the American Civil War.
Some Civil War documents indicate that the Confederate States of America controlled the area until the winter of 1861.
Wetland species include flocks of swans, geese, and ducks that use the sheltered area for feeding and resting.
The first English resident of the island was Giles Brent, who settled here in 1649 with his wife, Mary Kittamaquund.
She was the daughter of the paramount chief, or Tayac, Kittamaquund, who led the Piscataway nation, the most powerful on the north shore of the Potomac and one to which other tribes were tributary.
