The Keeper: Cantankerous, charismatic and passionately committed, this river keeper -- John Lipscomb -- reflects on his 25 years patrolling the Hudson, traveling more than 80,000 miles, by wooden boat, helping defend America’s First River.

Directed by writer, filmmaker and adventurer, Jon Bowermaster, a six-time grantee of the National Geographic Expeditions Council. Jon has written eleven books and produced/directed more than thirty documentary films. His feature documentaries include ‘Dear President Obama,’ ‘Antarctica, on the Edge,’ ‘After the Spill’ and ‘Ghost Fleet.’

Jon lives in New York’s Hudson Valley. He is the President of the One Ocean Media Foundation, Chairman of the Advisory Board of Adventure Science and Creative Affiliate of The Safina Center. For the past several years, Jon and his One Ocean Media Foundation / Oceans 8 Films team have focused on a series of short films about the environmental risks to, and hopes for the Hudson River Valley, the birthplace of the American environmental movement.

The Keeper was scored by one of The Grand’s expert sound engineers, Ben Zebelman.
