Control Point Locations
The City of Spearfish Engineering Department has established a network of survey control point monuments throughout the City to aid local surveyors and engineers in coordinating their work with the established City horizontal and vertical datums. The control point monuments have established coordinates on the city grid (NAD 83 / NAVD 88), and are periodically recovered by City surveyors to ensure that these monuments have not been disturbed.
