The Mississippi reaches its western most point in the vicinity of the county line between Adams and Hancock Counties. The river that defines Illinois’ western border has carved out a river valley that extends from five to fifteen miles wide bordered by hills or bluffs that are harder to erode than what once occupied the river valley. Along the Mississippi River in Adams County there is a belt of bottomlands ranging from one to five miles in width except for an approximately two length in the vicinity of Quincy where the bluffs overlook the river.
