Note:09/23/1969 {End of year synopsis} Averaged about one eruption / day. Went as long as 3 days occasionally. If Bear Den erupted about the time Ebony was ready to erupt, Ebony often delayed several hours. Sometimes, both erupted at same time. Bear Den erupted about 2 times for every eruption of Ebony. Ebony averaged about 15-25 ft. on any eruption that I observed this summer. (JB) Got a water sample at Ebony during and eruption (Sept 23.) for Bob Fournier to analyze. Could see no predictable pattern to Ebony. Often surged H2O 1-3 ft at frequent intervals for several hours before erupting, and then might not erupt if Bear Den played. Other times, appeared very calm and suddenly erupted.
