context_page_description: Warren County lies in western Indiana between the Illinois state line and the Wabash River in the United States. According to the 2010 census, the population was 8,508. The county seat is Williamsport.
  Before the arrival of non-indigenous settlers in the early 19th century, the area was inhabited by several Native American tribes. The county was officially established in 1827 and was the 55th county to be formed in Indiana.
  It is one of the most rural counties in the state, with the third-smallest population and the lowest population density at about 23 inhabitants per square mile. The county has four incorporated towns with a total population of about 3,100, as well as many small unincorporated communities. The county is divided into 12 townships which provide local services.
  Much of the land in the county is given over to agriculture, especially on the open prairie in the northern and western parts; the county's farmland is among the most productive in the state. Nearer the river along the southeastern border, the land has many hills, valleys, and tributary streams and is more heavily wooded.
context_section_description: The Wabash River, coming out of Tippecanoe County to the east, defines the southeastern border of the county; the terrain here is hilly and wooded areas are common.  Fountain County lies across the river.  By contrast, the northwest region consists mainly of flat prairie farmland; this continues in Benton County to the north.  Along the western side of the county is the border with Vermilion County, Illinois.  The small southern border is shared with the north end of the similarly named Indiana county of Vermillion.  The state capital of Indianapolis lies about 70 miles (110 km) to the southeast.
  The highest free-falling waterfall in the state, Williamsport Falls, is located in downtown Williamsport; a stream named Fall Creek flows through the town and falls 90 feet (27 m) over a sandstone ledge less than 1,000 feet (300 m) from the county courthouse. Northeast of Independence is the Black Rock Barrens Nature Preserve, a rare siltstone glade area that, with the adjacent Weiler-Leopold Nature Reserve, supports a diversity of flora including sessile trillium, phlox and wild hyacinth in the moist lowlands and serviceberry, rue anemone, birdsfoot violet and yellow pimpernel on the drier slopes.  Big Pine Creek is the county's largest waterway after the Wabash River, and 10.5-mile (16.9 km) segment of it is designated by the Indiana Department of Natural Resources as a state natural and scenic river and passes near Fall Creek Gorge Nature Preserve, an area of cascades and potholes.
  According to the 2010 census, the county has a total area of 366.40 square miles (949.0 km²), of which 364.68 square miles (944.5 km²) (or 99.53%) is land and 1.72 square miles (4.5 km²) (or 0.47%) is water.  Elevations in the county range from 480 feet (150 m) above sea level where the Wabash River enters Vermillion County to 830 feet (250 m) in northeastern Prairie Township.  The landscape consists mostly of flat or gently sloping moraine overlaying silty and loamy glacial till, except along the Wabash River where sand, gravel, sandstone and shale are exposed.  Various forms of silt loam constitute most of the county's soil and are conducive to agriculture.  Forests cover about 14% of the county, mainly around major waterways, and consist principally of deciduous hardwoods among which maple–beech and oak–hickory forests are the most common.  The only coal mines in the county are located in the southeastern part of Steuben Township, near the Wabash River.
  When the county was formed in 1827, it was divided into four townships: Medina,  Warren, Pike and Mound.  Over the following decades, many changes were made to the township borders and eight new townships were created.  Pine and Washington were the first of these, in March 1830;  Steuben followed in 1834.  Liberty was formed in 1843, Adams in 1848, then Jordan in 1850.  Kent and Prairie were the last to be created, in 1864.  As of 2010, Prairie Township, at 5.4 inhabitants per square mile (2.1/km²), has the lowest population density; it covers more area than any of the other townships—nearly 50 square miles (130 km²)—and contains no incorporated towns.  The highest density is in Washington Township, which has 120 inhabitants per square mile (46/km²); it includes Williamsport, the county's largest town, and covers only about 20 square miles (52 km²).
  There are four incorporated towns in the county.  The largest is Williamsport, which is on the western banks of the Wabash River in the eastern part of the county, just downstream of Attica (which is on the east side of the river in Fountain County); in 2010, its population was 1,898—nearly one-fourth of the county's total.  West Lebanon is about 5 miles (8.0 km) west of Williamsport on State Road 28, with a population of 723.  The town of Pine Village lies about 11 miles (18 km) to the north of Williamsport where State Road 55 intersects State Road 26, near the northern edge of the county; 217 people live in Pine Village. State Line City is in the southwestern part of the county and shares its western border with the Illinois state line.  A small Ill
