Grímsvötn
Grímsvötn volcano and the Grímsfjall mountain (1725 m high) are located south from the center of the Vatnajökull glacier. There is a lot of geothermal heat there so the glacier is melting constantly and the melting water gathers up in the crater. When the water level has reached a certain level it breaks out of the crater subglacial and down to Skeiðarárjökull glacier and Skeiðarársandur floodplain. Though the water is inside the glacier it never freezes because of the geothermal heat and activity.
