| Comments: | "The eruption of July 22 began after River Vent pauses. Also during that eruption a slender jet of water 12 to 18 feet tall could be seen between Upper and Lower Mortar! This came from an existing fracture [Bottom Vent?] which appears to be getting larger. That could prove very interesting." |
