| Note: | NOTE no date no time – end of month report - Several pools in the basin dried up during the period of dry weather which prevailed during most of August. The boiling muddy pool just North of the Black Growler ceased to overflow and became a typical mud pot. Colloidal Pool stopped overflowing and several pools to the west of the path in the basin which were fed by its overflow declined until the water level had fallen eighteen inches. |
