| Once the gas-saturated magma is ponded and retained in a holding reservoir, it will cool and crystallize, causing further degassing. |
| At one particularly dry location, surface water had ponded in the 45 mm rut, effectively preventing the drying mechanism postulated. |
| The south side of the subgrade culminated in a ponded ditch, which after the derailment contained water to a depth of one metre. |
| Our data consistently indicate that the magmas accumulated and ponded at shallow levels beneath the volcano. |
| During the Younger Dryas it appears that meltwaters ponded up on the southern edge of the ice sheets forming Lake Agassiz. |
| It stood erect and held back sediment and water until the water ponded upstream to a depth of 1.4 to 1.6 feet. |
