Ice Cave In Skaftafell, Iceland
Ice caves are temporary structures that appear at the edge of glaciers. They look amazingly beautiful from the inside. This particular cave is located on the frozen lagoon of the Svínafellsjökull glacier in Skaftafell, Iceland. The centuries old ice coming down the slopes of Öræfajökull via Svínafellsjökull glacier has metamorphosed into highly pressurized glacier ice that contains almost no air bubbles. The lack of air means that it absorbs almost all visible light, apart from the blue fraction which is then visible to the naked eye. The waterfall melts a hole into the glacier while the ponded water drains towards lower elevations by forming long ice caves with an outlet at the terminus of the glacier. The fine grained sediments in the water along with wind blown sediments cause the frozen meltwater stream to appear in a muddy colour while the top of the cave exhibits the deep blue colour. The cave is accessible through a 22-foot entrance on the shoreline. At the end it tapers to a tight squeeze no more than four feet high. Ice caves are in general unstable things and can collapse at any time. They are safe to enter only in winter when the cold temperatures harden the ice. Even so one could hear constant cracking sounds inside the cave. The cave is accessible through a 22-foot entrance on the shoreline.
