1990 Map of Triangle

USGS Topo · Published 1990

About this map

The Owyhee Mountains dominate this high-desert landscape in southwestern Idaho, a region defined by deeply incised canyons and high basalt plateaus. At the time of this 1990 revision, the isolated settlement of Triangle and the riverside community of Grand View serve as primary landmarks in a territory largely shaped by the cattle industry and legacy mining. Resource extraction is evidenced by the Black Warrior Mine and Bluebird Mine, located among the complex drainage networks of Silver City and Jordan Creek.
