|North Goggle is connected to Lion Geyser and closely connected to Goggles Spring. On periods of about 10 minutes, Goggles Spring and North Goggle Geyser rise and fall. At the top, of the cycle, the water over North Gaggle bounces up and down causing a slight overflow. A few bubbles may also rise to the surface. After about 30 seconds of this, the water drains back down the vent. Even if there is no eruption, this behavior is interesting to see. Eruptions come when the water level rises and stays up. First bubbles start to rise and then the water begins to boil. If it is going to erupt, the boiling will increase as will the overflow, until the eruption starts.
