About this map

Crystal Lake serves as the central focal point of this Hancock County landscape, providing a natural anchor for the small lakeside settlement that shares its name. The terrain reflects the deep integration of agricultural engineering and hydrology, where natural watercourses like the Boone River and W Br Iowa River are supplemented by an extensive network of managed channels, including Drainage Ditch Number 39 and Drainage Ditch Number 1. These systems were vital for transforming the prairie into the productive farmland seen today.

Local history is preserved at the Crystal Township Cem located just west of the town center. The map documents a landscape defined by a precise section-line road grid, including Co RD r26 and Grant Ave, which facilitates access to named agricultural landmarks like South 80 Field. Tributaries such as Plum Cr and Lindsey Cr meander through the northern and western reaches, illustrating the original drainage patterns of the region.
