| Comments: | After Grotto started Grotto continued to get a bit taller. When it was about half its tallest height it started toBecome steam driven for about 3 or 4 minutes. Was very tall, was much taller than when it was just water. After a minute off Grotto Fountain started bursting again to 8 feet, duration 45 seconds. |
