The DAUPHIN event was detonated in hole U9cq of the Nevada Test Site. The DAUPHIN device had a depth-of-burial (DOB) of 319 m in the Tunnel Beds Tuffs of area 9, about 200 m above the Paleozoic formation and about 300 m above the standing water level. Stemming of the 2.44 m diameter emplacement is described. A log of the stemming operations was maintained by Holmes & Narver. Detonation time was 08:50 PST on November 14, 1980, and collapse progressed to the surface at about 27. 5 minutes after the detonation resulting in an asymmetric crater having a mean radius of 71.9 m and a maximum depth of 13.0 m. No radiation arrivals were detected above ground and the DAUPHIN containment was considered successful
