| Comments: | Before this there may have been unobserved eruptions in Jan/Feb 2010 two confirmed eruptions somewhere between April and June 2010 and spotty activity in 2011 as inferred by washed/disappeared markers and occasional bacterial mat disturbance. Visitor report of an eruption on this day {no time given but assuming daylight} that was 60 ft high 30 ft wide and "very loud." Bill Warnock notes on Oct 28 that the area was "one huge pond larger than before of murky gray water with ejecta mainly towards the river. There is some on the boardwalk as well. There were two places in Wall area with intermittent boiling." On Oct 29 Warnock notes: "The new unified muddy gray pool was down slightly from yesterday and rocks were visible in the area of Black Opal and the rocks west of Wall were visible just under the surface. Another change: yesterday 'Salt and Pepper' down near the river was white in the right vent and gray in the left vent {when viewed from the parking lot}. Today both were brown-black and more vigorous." |
