| Comments: | MA Bellingham relays a visitor report of an eruption 10 to 20 minutes before she arrived at 1140: "I asked ‘60 [ft]’? and the man replied that was accurate. He said flying rocks were visible in the eruption and the water was very dirty...The small boys with him did excitedly confirm it was ‘Big!!’" |
