| Comments: | "An estimated 15 feet high dark vertical single blast out of the deeper part of the pool about 15 feet wide lasting about 6 to 10 seconds. The major uplift was about 12 feet high with several spikes or plumes of water a few feet higher. The entire mass of water dropped back into the pool creating a wave over a foot high. Very little water hit the north shore within several seconds most of the runoff ran into the next lower pool on the east...Only a very minor vertical spike was recorded on the thermistor in the pool at the time of the eruption." |
