Site U-4d: Original and GIS Surface Effects Maps

Explanation: These maps show the surface effects caused by the Latir (U-4d) detonation in the Yucca Flat testing area of the Nevada Test Site. The original hand-drawn “mylar” map (left) is compared to the GIS digital reproduction (right). Red and green dots are detonation sites that were mapped and not mapped for surface effects, respectively. Symbols and colors depicting GIS surface effects are: Sink (magenta), crack (black), fault (brown), pressure ridge (turquoise), and Yucca Fault (green). Mercury Highway trends north-south at right on maps.
