An estimate from public maps (USDA crop maps 2021–2025 averaged, LANDFIRE vegetation), not a survey of the ground. Maps can't see garden plantings, understory density, other beekeepers' hives, or this year's weather. The point is the Census Bureau's published center of Rock Falls (41.7721, -89.6942); a yard a mile or two away can differ, so check your own spot. The FEMA flood map was not checked for this page.
