Eruptive series of Black Hole Geyser. Intervals were short in the middle (10-30 seconds) and long (1-5m) at the beginning and end. The height increased until it peaked about a third of the way through reaching 8-9 feet and then weakened near the end. Durations were consistently 8-12s. Full data set will be posted later. |

Based on wash and wet runoff coming down from the crater. There were probably several more eruptions prior to 0954 |
