The interstellar medium has a thick disk structure (|z | ≲ 1500 pc, the ECL or extracloud layer) with a thin zone of cloud contamination at |z | ≲ 100 pc. The properties of all components other than clouds (e.g. cosmic rays, magnetic field, extracloud matter, pressure) drop slowly with |z| across the thick distribution, giving this layer a very important influence in the evolution of superbubbles. It seems likely to quench blowout or breakout and virtually all fountain activity. The weight of this layer stabilizes the clouds at low z; its high pressure and low density provide a cushion for impacts of infailing clouds.
