2018 Map of Tunnel Spring

About this map

Tunnel Spring and other critical water sources define the survival infrastructure of this high-desert landscape in the modern era. The terrain is structured by prominent geological formations, including the Sahwave Mountains in the east and the northern reaches of the Nightingale Mountains in the southwest corner. Between these ranges, the elevation shifts across the Granite Springs Ridge, while drainage is carved by the Sage Hen Wash as it flows south into Sage Hen Valley. This survey documents a complex network of springs, including Upper Stonehouse Spring and Lower Stonehouse Spring, which are often the primary focal points for ranching and wildlife in an otherwise arid environment. The map provides a clear record of the relationship between these remote water points and the deep relief of Stonehouse Canyon.
