Agricultural fields and deeply carved ravines define this portion of Knox County as it appeared in the late 1970s. Produced in cooperation with the Bureau of Indian Affairs, this orthophotoquad provides a direct visual record of the land surface, revealing the intricate drainage patterns of Howe Creek as it winds through the center of the map. Unlike a traditional topographic sheet, this imagery-based map shows the precise footprint of every farmstead, shelterbelt, and tilled field during the summer of 1977. The contrast between the flat upland plateaus and the heavily eroded slopes leading down to the creek reveals the complex geological transition of this Nebraska landscape.
