The project which has already been authorized by DMA and is planned for
drilling and detonations of HE shots in the U-12E tunnel between 4 March
and about 3 April of 1960 is another set of studies to look at the de-coupling
effects of various types of explosions in different media with different
tamping procedures. The results will be compared with Cowboy, and
the signals of Rainier, Blanca and Logan are mentioned as something to be
looked at for comparison. The report states "at a depth corresponding
more or less to Rainier and
Cowboy,
two shots of different sizes will be
detonated in order to check on the scaling laws. The third shot, ata
relatively shallow depth of burial, will test the extent to which the overburden
pressure influences the distant seismic signal.'’ The test organization for
the shot to be conducted by LRL shows Mr. M. Knapp and Mr. Vey Shelton
to be the Technical Director and Alternate,
respectively.
