SWIMMING TO THE TOP OF THE TIDE

A fluently rendered ode to tidal creeks and salt marshes and to a life in their embrace.

In this celebration of the Great Marsh, New England’s largest remaining continuous stretch of salt marsh, painter and writer Hanlon melds the sensibilities of a Southern California childhood with those of a 40-year resident of coastal Massachusetts. She also compares this complex ecosystem to those of the vastly larger Mississippi Delta and a Bahamian reef. Science is a key element in the book, but the narrative is viewed best as an account of the experience of four seasons of immersion in the flora, fauna, and tides of extensively protected marsh. Her realm may at times be turbid, but her prose is clear—graceful in its descriptive power though allowing for the occasional tributary into lyricism. The first half of the book is about exploring the same landscape repeatedly year-round, accreting knowledge of an estuary: its cycles, processes, and patterns. Hanlon provides a biologic (and microbiologic) cross section of the salt marsh habitat, the grasses that fortify it, and the fauna that subsist on its largesse. In the second half, the author reflects a need to understand “something of our current cultural and evolutionary moment, with both its tragedies and its possibilities.” Hanlon understands how our moral imagination exerts a profound influence on our thoughts, attitudes, and actions, and her various warnings on the rising threats facing vital marshlands nationwide are no less important for being familiar. Also coursing through this tale are the currents of her marriage and shared passions with her husband, also an artist, with asides on their custom wood furniture business, children, and grandchildren. Readers not especially enamored of the idea of swimming in tidal creeks and rivers day after day may find portions of the book a bit monotonous—but not if they appreciate the theme of deep human integration in the natural world.

Hanlon’s observations are as gently propulsive as the rhythmic stroke of a swim fin.
