About this map

The Little Sioux River valley defines the eastern edge of this Woodbury County landscape, where the small settlement of Oto is situated near the junction of Fern Creek and Miller Creek. The river's historical path is visible through the Old Channel and the isolated curve of Horseshoe Lake, illustrating the shifting hydrology of the Iowa Loess Hills region. In the western uplands, the agricultural pattern of Grant township is marked by scattered civic and religious landmarks, including the Townhall and Bethel Ch.

Genealogists will find notable value in the location of rural burial grounds like St Marys Cem and the Oto Cem. The map provides specific detail on the drainage systems of the area, naming several smaller tributaries such as East Fork Wolf Creek, Moose Creek, and Smoky Hollow Creek. An engineered Spillway indicates water management efforts near the center of the township during this era of late-1960s land use.
