About this map

The Illinois River serves as the central artery for this portion of Marshall and Putnam Counties, shaping a complex landscape of backwater lakes and riverfront commerce. The valley floor is dominated by significant water bodies such as Senachwine Lake, Billsbach Lake, and Goose Lake, while the upland bluffs are dotted with numerous rural institutions. These include one-room schoolhouses like Brush College Sch and Sprinkleburg Sch, alongside landmarks such as the Whitefield Town Hall and Salem Ch.

Railroad infrastructure, specifically the Chicago and Pacific and the Chicago Rock Island and Pacific, dictates the location of primary settlements. The town of Henry sits at a critical junction where the river meets the rail line, while Lacon and Sparland anchor the southern reach of the map. This survey, compiled from early Air Corps aerial photography, details the precise layout of local infrastructure before mid-century modernization, preserving the locations of family-associated burial grounds like Sugar Grove Cem and Bonham Cem.
