Kendall County is a small but rapidly growing county that
has the majority of its population in the northeast and along the Fox River
(the only river in the county), which runs through the county's northwestern
section. Many new subdivisions have been constructed in this county, which has
produced considerable population growth. Southern Kendall still remains largely
agricultural. Kendall County has two primary ranges of low-lying hills formed
by what is known as an end moraine. Ransom, the more predominant of the two
moraines, runs through the west and north-central part of the county. This
moraine has created elevations over 800 feet (240 m), in contrast to elevations
in southern Kendall County that drop to the lower 500-foot (150 m) range.
Minooka, the other major end moraine ridge in Kendall County, runs along its
entire eastern border with Will County. The two moraines intersect at almost a
right angle in the township of Oswego. The county's only designated state park
is Silver Springs State Fish and Wildlife Area.
