As far as I know, Vault is always full when Giantess starts.

Just a quick question--has Vault ever drained before Giantess Geyser started erupting (thus being somewhat of an indicator of an impending Giantess eruption)? Or is it most always simultaneous or shortly after the start? Pat Snyder On Jan 31, 2010, at 6:11 PM, Lynn Stephens wrote: Just a note about water levels in Vault and Giantess. Vault starts draining with the start of Giantess. The initial eruption comes from an "empty" crater. Just before the Vault initial, audible thumping is heard before you can see the rising water level. The water level pulsates up and down once it starts coming into view. With each pulse it seems to rise a little higher. Within a couple minutes it reaches overflow and then the eruption starts. -------------- next part -------------- An HTML attachment was scrubbed...
