Between the St. Mary's River and Jacksonville US 1 passes over the eastern edge of the Trail Ridge, the watershed of the peninsula, for approximately eight miles. From here the Ridge section slopes into the flat woods area of northeast Florida. Few people live in this section of the State, and except in the three small towns, few houses are seen along the route. There are dense hammock lands along the river at the northern end of the route, and evergreen pinelands border the highway.
From the white concrete bridge spanning the ST. MARY's RIVER, 0 m., an excellent view is afforded of the deep narrow stream and its wooded banks. All types of bay vegetation grow along the water's edge, the sweet and black gum, magnolia, swamp holly, poplar, several varieties of oak, elm, ash, willow, cedar, and some slash pine., Bamboo vine, yellow jessamine, Virginia creeper, and wild grape enmesh the trees and cling to some of the shrubs and underbrush. Here mistletoe is found clinging to the black gum, and palmettos grow in profusion. Prickly ash, elbow, and hurrah bushes are common. Flood tides have cut deeply into the, high banks of the river and many of the trees droop precariously over the water.
Usually the St. Mary's is a peaceful little stream exhibiting temperament only in swirls and eddies as it twists and turns through the semitropical forest; but after a period of rains the river becomes a raging torrent lashing at the trees and shrubs along its banks. During these times the normal depth of eight ft. at the bridge increases to 18 or 20 ft.
The drab coffee-colored water was formerly in demand by the masters of four-riggers and tramp steamers docking at Fernandina,
