Into the depths of the earth: Cave network in the heart of Vietnamese jungle is so large its end is yet to be found
This recently discovered cave in Vietnam is massive beyond description. An entire forest is growing inside! There are no words to describe the enormity, and beauty of this natural wonder. The Empire State Building will fit inside!
This up to 1000 years old snow has metamorphosed into highly pressurized glacier ice that contains almost no air bubbles. Thus it absorbs the visible light despite the scattered shortest blue fraction, giving it its distinct deep blue waved appearance. This cavity in the glacier ice formed as a result of a glacial mill, or moulin. / Svínafellsjökull glacier in Skaftafell, Iceland
