| Note: | 04/20/1973 Echinus : water very turbid gray- almost to the point if being opaque. One eruption was observed and timed. Duration: 3m48s estimated max height 70 feet which occurred near the end of the eruption. Several times there seemed to be almost a pause in the activity and play would start in again. {No time listed} |
