| Note: | 09/10/1971 Pearl Geyser – pool is also clear as usual but surface is much more agitated by waves and pulsations than normal. This evening occasional steam explosions from below were able to burst to the surface and shoot water as high as 3 feet – which is the first time for at least the past 2 summers. |
