Occasional tennis ball size bubbles in center of the clear pool - Upwelling by the center ledge on E side - small strings of bubbles regularly came up from under the two E ledges either side of that that looked like tiny vortexes but I thought it was a trick of lighting! Hard to photograph due to drifting steam and backlighting but my photos seem to confirm these tiny whirlpools all lined up! Neat. = Three Trees pushing out hot water but no splashes seen or heard |
