| Note: | From Geologic & Thermal Highlights of YNP 1983-1984: no times given May 10, 1984, when it was again observed having muddy eruptions laterally at least as far as four meters to the north. No accurate intervals or durations have yet been determined, but they appear to be similar to those logged during June and July of last year. |
