1989 Map of Riddle

USGS Topo · Published 1990

About this map

The Duck Valley Indian Reservation dominates the southeastern quadrant of this late 1980s landscape, where the Idaho-Nevada border country transitions from high volcanic plateaus to deep canyon systems. High-elevation tablelands like Lambert Table and Brace Flat are dissected by the dramatic drainage of the Owyhee River and the Little Owyhee River, reflecting a terrain shaped by intense erosion and seasonal water flow.
