Eruption Detail

There were likely more experienced observers present but for what it’s worth- on returning from basin walk I got to steerage during strong overflow that never seemed to subside. Water came around the left side over the little waterfall three or four times in just a few minutes, so I went up to middle deck and caught the start. Wind absolutely pelted the decks so couldn’t get a great visual but sure heard and felt it. Lots of gravel in the deluge but did not notice any rocks, at least on the decks.
