The Wabash River dominates the city's geography, forming its western border. Small bluffs on the east side of town mark the edge of the historic flood plain. Lost Creek and Honey Creek drain the city's northern and southern sections, respectively. In the late 19th century (particularly during the oil craze of 1889), several oil and mineral wells were productive in and near the center of town. Pioneer Oil of Lawrenceville, Illinois, began drilling for oil at 10th and Chestnut streets on the Indiana State University campus in December 2013, the first oil well drilled in downtown Terre Haute since 1903.
