especially in the south, that are level and have extremely poor drainage. Eastward again, there is a stretch that ranges from a few miles in the extreme northern areas to about 6- wide in the southern area, including Hilliard and much of County Road 108 and State Road 301. This area again has very poor drainage, low-lying land, and fairly sandy soil. East of this are scattered areas of high, sandy land with spotty or poor drainage. East of this, there is an area including Callahan with very sandy soil on top, and clay underneath. This section of the county is heavily permeated by small creeks and rivers, which bring with them low, poorly drained soils. This zone extends across the entire county from north to south at a fairly consistent width of about 3-, except in the north, where it widens to nearly across. East of this area is a large band of land with a consistent width of about . The land is low and level with extremely poor drainage, and it is permeated by small creeks and rivers. In the northern section, this is where some tributaries join the St. Marys River, while in the south a number of tributaries drain into the Nassau River, which flows into the Nassau Sound and the Atlantic Ocean. East of this area is a section of land about in width that has extremely sandy soils with bad drainage all around. Further eastward is a large area, including Yulee and O'Neil, about in width, with poor drainage and sandy soil at higher elevations, pockmarked by large areas of low lands with even worse drainage. To the south is an area of low-lying, organic soils which are essentially marshes and wetlands along the northern bank of the Nassau River, continuing into the Nassau Sound. Still eastward and somewhat to the north is a large area of marshes and organic soils which characterize area wetlands. There are many small islands in this area, and it is permeated by the Bells River and Jolly River, which empty into the Cumberland Sound to the north, just below Cumberland Island. Amelia Island, the easternmost section of the county, is characterized by poor drainage in the west and better drained, higher, sandier land as one travels eastward towards the beach. The northern area of the island features salty marshlands surrounding Egan's Creek, which runs directly beneath Atlantic
