The Mohegan Indians knew it as Aquehung or "River of High Bluffs." We know it as the Bronx River. The roughly 24-mile river runs deep with history, a history that includes a whole lot of pollution. On this week's Cityscape we're talking with Maggie Scott Greenfield, the Executive Director of the Bronx River Alliance. The organization is committed to protecting, improving and restoring the Bronx River corridor.
