About this map

The Mississippi River forms a dominant boundary along the western edge of this landscape, carving a complex network of islands and backwaters such as Big Soup Bone Island, Little Soup Bone Island, and Railroad Island. This modern survey reveals a highly specialized river environment preserved within the Upper Mississippi River National Wildlife and Fish Refuge, where seasonal changes dictate the visibility of features like Santa Fe Beach and Savanna Bay.

Inland, the terrain rises sharply into the uplands of Jo Daviess and Carroll Counties. Small settlements and historic landmarks anchor the rural road network, including the community of Derinda Center and several legacy burial sites such as Trinity Lutheran Cem and Massbach Cem. The drainage patterns of Rush Creek and Camp Creek define the ridges and valleys, illustrating the transition from the fertile river bottoms to the rolling agricultural hills of Northwest Illinois.
