1981 Map of Jumpoff Hill

The presence of numerous named water sources like Empey Spring and Cattle Creek highlights the importance of water management in this high-elevation region. To the east, the landscape transitions toward Homer Ridge, while smaller drainages like Hell Creek and Dan Creek feed into the larger basins. This map reflects a moment in time when the area remained primarily used for watershed and grazing, with few permanent structures but a dense network of topographic landmarks used by locals and land managers.
