2021 Map of Greeley Flat

About this map

The N Fork Little Humboldt River carves a winding path through this high-desert landscape in northern Humboldt County. This 2021 topographic survey reveals a terrain defined by subtle drainage patterns and seasonal water storage, centered on the broad expanse of Greeley Flat. The presence of Big Sage Reservoir and Sagehen Reservoir suggests a pastoral reliance on water management in an otherwise arid environment. Along the northern margins, the Little Owyhee River enters the Owyhee Desert, marking the transition between major drainage basins. For researchers, the map provides a clear view of the modern rangeland infrastructure, including isolated water sources like Antelope Spring and the distinctive contours of the Red Hills to the south. Small, localized features such as Evans Lake illustrate the specific hydrology of this sparsely populated corner of Nevada.
