This is the story of a tree.

A mighty wonder that graced the forests of Appalachia and sustained all forms of life, nurtured communities, and fostered craft and culture.

Gave rise to great cities. Embraced us, from cradle to grave.

At the turn of the 20th century, a deadly blight was accidentally imported into the U.S. from Asia. It devastated the American Chestnut, killing billions of trees throughout its native range, from Maine to Alabama. Within a span of only two generations the American chestnut was eliminated as a mature forest tree.

This is the story of people.

Citizen scientists and researchers have worked tirelessly to restore this economically and ecologically important tree species. The new documentary film, Clear Day Thunder: Rescuing the American Chestnut, tells the story of these passionate people during a pivotal moment in this effort to bring the tree back from near extinction.

This is the story of promise.

The tree that forged a connection with humankind has been embraced in turn by humans who, invigorated by hope, are working tirelessly to revive this magnificent tree so that it can once again help shape the future.
