| Note: | FYI, Steamboat has a 2-holed vent located SW of the S vent and across from S vent's runoff channel that huffs steam during S vent minors and erupts or sloshes water intermittently sideways but also slightly vertical (a few inches max) during a major. I have been calling it the SW vent but it probably has other nicknames. This vent stopped sloshing water at 1442. Since the transition from water to steam phase in Steamboat's other vents is highly subjective, I propose that the water phase ends when the SW vent stops sloshing water out as it did during all of the eruptions that I witnessed this year. |
