2015 Map of Greenbush

About this map

Greenbush and Youngstown anchor this agricultural landscape along the border of Warren and McDonough counties. The terrain is defined by a dense network of drainage systems, including the intricately branched Swan Creek and the meandering Drowning Fork to the south. The presence of several family-named burial sites, such as Pierce Cem, Bond Cem, and McMahill Cem, provides a map for genealogists tracing early settlement patterns in this part of Illinois. A significant reservoir, Little Swan Lake, breaks the grid of rural roads near 23rd Ave, reflecting how modern water management has shaped the local topography alongside natural features like the N Fork La Moine River. The strictly rectangular road grid, including Greenbush Rd and Wolf Rd, underscores the enduring influence of the Public Land Survey System on the regional layout.
