This trip was to dig a vault for a seismometer. A 4ft hole was dug on the west side of the building, and a 1.5" conduit was buried between the vault and the building. A hole was cut in the side of the building for the conduit. Another trip will be needed to install the electronics and sensors.

inside tank was at 10", refilled to 21" before losing. Outside tank is at 63"
