Very rare. Lambatungnajokull glacier's termination flows down into the Skyndidalur valley from the eastern edge of the Vatnajökull icecap. It probably was the first such natural phenomenum to be researched scientifically by an Icelander, Thordur Vidalin. His disseratation on the subject appeared as Schediasma de Montibus Chrystallinis Islandiae (Hafniae, 1695) and was translated into German in 1754. Eventually, it reappeared in Icelandic translation in 1965.
