Inspired by Pete Seeger's desire to clean up the river over forty years ago, The Great Hudson River Revival initially helped raise the funds to build the sloop Clearwater, which has since become a world-renowned floating classroom and a symbol of effective grassroots action. Today, Hudson River Sloop Clearwater, Inc. is a non-profit organization that sails at the forefront of the nation's environmental challenges. The revenue raised by the Revival goes to support Clearwater's numerous educational programs and its work toward environmental and social justice—as well as keeping the sloop Clearwater afloat.
