Triggered by a series of small tremmors in the area in 1996 Botryoidal became a very fun geyser to watch. Prior to this, Botryoidal behaved as small perptual spouter. Since 1996 it has been a true geyser characerized by explosive eruptions. Its fountain-type eruptions start explosively, lifting the entire pool of water above the crater rim before the steam driving the eruption finally has chance to burst through the water. The eruptions reach about 10 feet, durations are about a minute and intervals are about 3 to 5 minutes. Activity since 1996 has remained pretty much the same though some minor variations have been seen.
Botryoidal is easily visible from the road to Great Fountain Geyser.
