-“Yueca Basin is a valley roughly 10 X 20 miles extending northward from the Control Point. It has considerable relatively level land, and an extensive dry lake on which an air landing strip has been laid out. Near the Control Point end of the basin are News Nob and other official observer sites. Twelve firing sites have been laid out in the basin. Developed sites may have instrumentation towers, underground instrumentation bunkers, other types of recording equipment and structures, and such items as rocket launchers and mortars used to put up trails or puffs of smoke useful in making measurements. Areas have been developed for air drops and for tower, surface, tunnel, and balloon place- ments. Some areas are suitable for more than one such type of placement. -31- COPIED29 Lik pg
