About this map

Missouri Valley serves as the focal point of this Harrison County landscape, where the flat Missouri River floodplain meets the rising elevation of the Loess Hills. This transition in topography is marked by several small settlements and rural crossroads, including California Junction and Findley. The hydrology of the region is complex, defined by engineered drainage and natural remnants like Fish Lake, Nobles Lake, and the meandering path of the Boyer River. Extensive water management is evident through features such as Wilson Ditch and the channelized Allen Creek, which work to manage the alluvial soils of the valley floor.

Genealogists and local historians will find significant detail in the eastern bluffs, where Old Frazier Cem, Mount Carmel Cem, and Bose Hill Cem are situated away from the flood-prone lowlands. The survey also captures modern infrastructure like the Missouri Valley Airport and the intricate road network, including Lawton Trl and York Rd, which navigate the varying elevations between the river valley and the Loess Hills upland.
