The island demonstrates a continuing agricultural tradition rooted in Potomac River farming practices that shaped settlement patterns in this region. People who live and work here maintain land use methods tied to the water and seasonal rhythms.
Reaching the island requires water navigation since no bridges connect it to the mainland, and you need permission from property owners. Check access conditions ahead of time, as private ownership controls who can visit.
