About this map

Castro Ranch sits at the heart of this high-plateau landscape in Owyhee County, where the terrain is defined by distinct flat-topped formations known as tables. The geography is marked by the prominence of Castro Table, Black Table, and Star Ranch Table, illustrating a ranching-driven land use pattern that relies on scattered water sources like Swisher Spring and Camp Spring.

Drainage systems such as Deep Creek and Nickel Creek carve through the plateaus, creating unique geological features like the Nickel Creek Pocket and the steep-sided Bull Gulch. Human infrastructure is sparse, characterized by the winding path of Grasshopper Rd and the presence of Bower Reservoir to the north, suggesting the importance of water management in this semi-arid high country during the early 21st century.
