2021 Map of Oregon Canyon

About this map

S Fork Little Humboldt River defines the western edge of this high-desert landscape in Elko County, where the terrain transitions into a complex of ridges and seasonal watercourses. The topography is dominated by prominent elevations such as Castle Ridge and Pole Creek Ridge, which overlook the expansive Oregon Flat. This map documents a region where water sources are vital but dispersed, marked by isolated points like Castle Spring and Thousand Springs. Drainage patterns are clearly defined by numerous creeks including Milligan Cr, Brush Cr, and Frazer Cr, all contributing to the larger watershed of the Oregon Canyon area. The southern portion of the quadrangle is anchored by the Owyhee Bluffs, illustrating the dramatic vertical relief characteristic of this corner of the Great Basin. This 2021 survey provides a contemporary view of the land's physical layout, useful for tracing the natural landmarks of northern Nevada.
