some chunks have sloughed off of the shoulder vent - will compare photos from previous years - haven't yet stood there during its cycle to see if more or less water is spritzing out than other years but now am interested and will do that |

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. |

09/25/1971 Hurricane Vent has a line of 1 inch high bright yellow sulphur crystals being deposited from steam vents near the top NE edge of the Hurricane pit. In that the crystals are long, relatively separate from each other, and are in sharp contrast to the brownish purple soil below, I can honestly say that this is one of the most beautiful sights that I have seen in the basin all summer.
