Note:(New info has confirmed the eruption.) Getting unconfirmed reports of an eruption 4/19 at about 1630. Facebook post says maintenance worker saw water above trees. YVO graphs are down but Norris Museum seismograph shows noise at that time. Also YVO Tantalus Creek graphs -all 3 graphs under hydrology - show spikes. (See attached YVO graphs. Also see other notes on yesterday’s & today’s GT.)

4/20 around noon, Steamboat in steam phase, Cistern drained but not fully, silica on everything down past Cistern, trail washed out beside bridge beneath Steamboat.
