Comments:SV shoulder and back channel had flowing water on arrival at 0825. Activity progressed consistently throughout the day with only a few short lulls. Final push started around 1353 and slowly built over the course of two hours. SV began having sustained "fountaining" minors 20-30 min. prior to eruption. North followed suit and increased in volume, height, and vertical. There were at least two "wall of water" minors in the five minutes prior to the eruption. I did not note times because I was trying to record video and also brace for the incoming thunderstorm. Eruption at 1552 beat the onset of the storm by 2-3 minutes. The eruption was not that tall (for Steamboat) due in part to the high winds. Heavy rain gave way to two rounds of hail-sized hail during the 26 min. water phase. North transitioned to steam at 1618. It transitioned back to water 1700, followed by full pauses and restarts at 1701 and 1702. It again reverted to steam at 1708, then went back to water at 1710. It had additional pauses and restarts at 1711, 1714, 1715, 1717, 1718, 1720, and 1721. Total of nine pauses and restarts. Great rainbows and drenching of the platforms once the sun came out during steam phase. In full steam phase when I left just after 1800.

98th eruption of the current series.

Arrived a little after 10, having noticed a rather large steam column at Norris intersection coming from SB earlier that morning. My first noted activity was at 10:36 & 10:38 with concerted vertical minors with moderate, audible runoff (babbling brook). Russell reported stronger activity from earlier in the morning. At this point there was no choice but to stay! This activity continued throughout the morning; strong, SV dominated, ~50% concerted, occasional NV & SV vertical, with moderate SV runoff. There were several quiet periods of 15-20 minutes with no notable activity. At 13:58 activiy increased to slightly more concerted play, more vertical play from both vents and increased volume from SV. SV initiated most concerted minors, or were solo with increased girth, looking very "fountainous" as described by CB. Runoff was also remarkably improved to Heavy (raging river). Several noted as H+ runoff. 14:56 noted as "huge SV fountain H++". Next note at 15:13 began a gradual increase in activity leading to another "SV fountain w H++" at 15:36 which was beginning of build up to eruption. 15:38, 15:41, 15:45, 15:48 and 15:50 and eruption at 1552. By 1600 we were being pelted by pea sized hail. l would add that the 3rd and 4th restarts were close to 200' IMO.
