Stemming of the 2.44 m diameter emplacement hole followed the plan shown in Fig. 1.4. A log of the stemming operations was maintained by Holmes & Narver. Detonation time was 08:15 PDT on June 12, 1985 and about 10 hours, 17 minutes later a sub-surface collapse progressed upwards to a depth between 200 and 270 m. No radiation arrivals were detected in the emplacement hole and the SALUT containment was considered successful
