Ochoco National Forest dominates this section of the Ochoco Mountains during the early 1990s, revealing a landscape defined by industrial water management and timber-land topography. The southern portion of the map shows the complex irrigation infrastructure of the Main Canal, Ochoco Canal, and Diversion Canal, illustrating how water was diverted from mountain drainages like McKay Creek to support the surrounding high-desert agriculture. Prominent peaks such as Hensley Butte and Cougar Rock serve as anchor points for a network of forest roads and springs, including the curiously named Bottleneck Spring. Several quarries and Gravel Pits are noted along Gerke Road, indicating the local extraction activity used for regional road maintenance and construction projects within the forest boundaries.
