This slide is from a presentation entitled "This is the Clearwater," created by Nancy Papish in cooperation with the Hudson River Archive. The Hudson River Sloop Clearwater, Inc. is an environmental organization that advocates for the protection of the Hudson River and its ecosystems. Animals and fish of the Hudson River Valley can be endangered by water pollution and irresponsible land use, a problem that Clearwater members try to share with the public. (Color slide)
