2010 Map of Big Valley South

About this map

McMillan serves as a central point in this rural landscape within Big Valley, where the winding Colorado River defines the local topography. This 2010 survey illustrates a region shaped by both natural watercourses and 20th-century water management projects, including the McDaniel Lake Dam and the Soil Conservation Service Site 11 Dam. The terrain is punctuated by significant elevations such as Wildhorse Mountain and Round Mountain, while the Mauldin Hills rise to the northwest. For those researching local heritage, the map identifies the Lower Valley Cemetery and McMillin Cemetery, providing essential coordinates for family history. The drainage network is particularly dense here, featuring the three prongs of Horse Creek—North Prong, Middle Prong, and South Prong—which converge as they flow toward the main river valley.
