|Comments:||"Waterfall Geyser" (= "North of Thumb Geyser"). Yay - my first Waterfall eruption! Small bubbler on the western edge of Waterfall's pool (the easternmost of the 3 features to the west of Waterfall) was active all afternoon. It got swamped by a Waterfall Geyser basin filling event at 1726 - pool engaged in slight roiling. Eruption from 1731 to 1810 (see attachments for still photos and video compilation). Bursting from 2 vents - usually one at a time. Highest bursts maybe ~7 feet high. Eruption runoff cascaded over rocky outcrop into Thumb Geyser - that basin filled up pretty well. Waterfall Geyser's basin slowly draining at 1813; back to pre-eruption pool level at 1816; pool level was way lower by 1820, partly exposing the large, central, irregularly-shaped vent area.|
