1959 Map of Bone Gap

A notable historical landmark is the Indian Treaty Boundary, which cuts horizontally across the terrain, reflecting the early surveying and land division history of Illinois. Local genealogy is well-preserved through several rural landmarks, including St Sebastians Ch, Lick Prairie Ch, and numerous family and community burial sites like Tanquery Cem and Wells Cem. The map also identifies the widespread presence of oil wells, indicating the importance of resource extraction to the local industry during this period.
