8/31/1994 - no time noted - After the Ledge eruption... Hurricane Vent has started an interesting eruptive pattern – first noticed Fri or Sat. There is a steam vent on the NE side of slope which will release a great amount of steam for 30 sec. After which water flows from a small 1” x 1/2” (?) square vent below the steamvent quite near the pool level. The rock around the water run off area is black in color – the water flows for 30 sec or so… Have seen series of eruptions & also single eruptions an hour or so apart. |

8/6/1988 Hurricane Vent In Porcelain Basin, Hurricane Vent has an upside down (for a geyser, that is) eruption. It’s eruption is preceded by increased steaming from the fumeroles to the north. After several minutes of increased steam, water overflows from a horizontal crack in the rock, which is about one foot long and about 1½ feet above the water level, on the north side. The water flows out for about 1-2 minutes. |
