This station consisted of a 12-inch diameter

schedule 160 steel pipe extending from the base

of a steel recording shelter to a point 10 feet
from the underside of the Station 1 cab floor.
The steel shelter was embedded in a 24’ x 24’ x
11’-thick concrete slab which provided footings
for the tower and an elevator pit for Station 1.
The pipe contained 15 instrument gages along
its length. The instruments were wired to a
recorder in the steel shelter at the tower base.
Grout was required inside the pipe and the
conduit carrying the instrument wiring was
filled with insulating material. Steel access platforms were installed at seven locations along the
pipes. A 25’x 25’ area of rock 2 feet deep was
placed over the top of the shelter to deflect
and absorb blast waves. No power was required.
Minus 1 minute and minus 15 seconds timing
signals were furnished.
