1985 Map of Rill Creek

About this map

Castle Valley and the dramatic drop of the Porcupine Rim dominate the topography of this mid-1980s provisional survey. The landscape is defined by its deep drainage networks, including Jackass Canyon and Negro Bill Canyon, which cut through the high sandstone plateaus. In the southwest, the Spanish Valley floor supports more modern local infrastructure, such as a Golf Course and Rodeo Ground, alongside a quiet Cem. The map documents a complex web of 4WD tracks and trails navigating the transition from the mesa tops at Johnsons Up On Top down to the creek beds. Water sources are critical in this arid environment, marked here by Rill Creek and various Springs that feed into the larger North Fork Mill Creek system.
