The detonation produced a cloud whose upper limit reach titude of about 123,000 feet (37.5 km) (Figure 73). The lowest (surface to 6,000 feet [1.8 km]) of the stem moved to the southwest at a speed of approximately 11.5 mi/hr (18.5 km/hr). The next higher 20,000 feet [6.1 km]) moved to the west-northwest at about 13.7 km/hr). The upper levels and the stem moved out to the north. the PPG, all levels probably moved out to the east except the lo els, which continued in a westerly direction.
