| Note: | 6/24/1990 Dark Cavern has small eruptions that reach or slightly exceed the rim about every two minutes. Each eruption lasts about one minute. After watching for ½ hour I saw one of its major eruptions that lasted about 4 minutes. Erupted vigorously from both vents & cleared the rim by 8-10 feet. |
