Hilger Valley serves as a southern gateway to this mountain landscape, where the Great Northern railway winds alongside the waters of Little Prickly Pear Creek. The map records the infrastructure of the early 1960s, including a prominent pipeline and a tunnel facilitating movement through the hills. To the northeast, the Missouri River is harnessed at Holter Lake, supported by a Powerplant and the Wolf Creek Gaging Station.
