Puff 'n' Stuff Geyser occurs in the Back Basin at Norris. It is very close to the wooden boardwalk and consists of a fissure-like
vent in the side of the gentle slope.
Puff 'n' Stuff Geyser makes a lot of noise, but doesn't seem to do much else!
The eruptions are only a few feet high and often send a fine mist down the boardwalk after you. Around the fissure, there
is often a build-up of a light grey-blue clay, perhaps formed by the interaction of the underlying rock with the hot mineral-rich
waters erupting from the vent.
The run-off from Puff'n'Stuff cools rapidly and plants quickly colonise this channel.
This can be a good place to sit and watch dragonflies darting around :)
Sticks lying in the outflow from the geyser rapidly become coated in grey-white silica. This is the first stage in the fossilisation
of plant remains in this area.
