A Fine Improvable Marsh (Historical Marker)

Here follows the inscription written on this trailside historical marker:

A Fine Improvable Marsh
George Washington Memorial Parkway
— National Park Service, U.S. Department of the Interior —

When George Washington surveyed the future site of Alexandria in 1749, he described this area as a “fine improvable marsh.” Do you think that ideas about improving marshlands have changed since Washington's time? How can we improve Dyke Marsh today?

The National Park Service has big plans for Dyke Marsh—to preserve what's left, to restore acres of wetlands, and to protect it from future threats. With hard work, what you see here can become an outdoor classroom, a vital habitat, a storm buffer, and a water pollution filter.

Dyke Marsh reminds us that our actions and attitudes are responsible for the quality of our environment. The future of Dyke Marsh is really up to all of us.

Erected by National Park Service, U.S. Department of the Interior.
