| Comments: | Very close to start if not the start. Logging it as ie because I don't know how Grotto Fountain's steam at the start looks. Over treetops by 1451. Steam diminished after Grotto's start until mid-1502. Thereafter it went within a jet to well over the treetops, sustaining until late-1505 before water dropped and steam diminished. |
