Matt captured this awesome video.

It’s about 8 minutes long.

Old Faithful erupted for ~ 4.5 minutes, and the rest shows Lion’s eruption... two geysers at once!

AWESOME!

“How many gallons of water are expelled during an eruption?

“It depends on the duration of the eruption. Scientists estimate that the amount ranges from 3,700 gallons (for a short duration of 1.5 minutes) to 8,400 gallons (for a longer duration of 4.5 minutes).”
