| Note: | Aug 4 1980 Ebony NOTE: after an eruption of Bear Den Ebony Geyser is quiet and then slowly builds up, making a chug[g]ing noise. This noise grows stronger and slows down from as high as 8’s a minute to 4-5 minutes before an eruption of Bear Den, Ebony will become totally quiet. Before a steam puff Ebony stops later, and not so completely 10-15 seconds before a steam puff Ebony may start to splash heavily inside the crater like a small eruption, and emit more steam |
