1972 Map of Kosoma

About this map

The Kiamichi River winds through this section of Pushmataha County, carving a valley between the high ridges of Kosoma and Blackjack Mountain. In the early 1970s, the landscape here was defined by the intersection of the St Louis San Francisco railroad and rural settlements like Kosoma and Finley. The area shows a transition toward more managed water resources, as notes from the margin indicate certain low-lying areas were subject to inundation by the Hugo Dam project during this era.
