| Note: | 51 Days Post Eruptive - Arrived to a decent amount of runoff at steerage. Concerted minor activity continued from 0659-0808 but then things slowed down with gaps of about 20-30 minutes between minors putting any runoff down the channel between 0903-1047. At 1134 we had a huge concerted minor, 40'-50', that was sustained for approximately 10 seconds. That got everyones attention. That was not followed up however, and things quieted down quickly. Minors were few and far between until 1510, when our of nowhere North and South shot up together with a huge volume of water out of south that washed a TON of gravel down the runoff channel. Again, it had no followup and no runoff was generated until almost 1605. USGS Temp logger shows a spike to 50° C as a result of this activity! Finally at 1745, there was one more concerted minor worth noting, with minimal followup and weak minors through 1857. At steerage, runoff is crystal clear and the strong minor at 1510 pushed the gravel around in the trough. |
