In the early 1960’s a developer sought out land on Mason Neck to build a planned community and airport. Elizabeth van Laer Speer Hartwell, a local resident, who valued the pristine nature of the peninsula, organized an effort to stop this development. She recognized the potential of the Mason Neck peninsula as a safe haven for the endangered bald eagles along the Potomac River.
