By Dan FannonIn the Highlands, the Hudson River flows through remarkably deep water past towering mountains with names like Dunderberg and Storm King. But in its northern reaches, the river changes character. The course widens and shoals as it passes the Hudson Valley’s verdant farmlands, forming flats, enormous miles-long islands of mud and silt just under the water’s surface.
The charts mark these areas as 3 feet mean low water, but it’s not unusual to find a thick carpet of green reeds and brown soil blanketing most of the river’s surface. Given the strong currents and turbulence from passing barges, being mired in the mud flats can quickly become life-threatening.
