Griggsville occupies the high ground of the western Illinois prairie, where a grid of rural roads connects family homesteads and local landmarks. The landscape is defined by the sharp descent from these uplands into the eastern river bottoms, marked by deep drainages like Hatch Hollow, Church Hollow, and Napoleon Hollow. This topography creates a natural boundary between the agricultural plateau and the navigable waters of the Illinois River, which forms the eastern edge of the survey.
