Jökulsárlón is the largest glacier lagoon or lake in Iceland. Situated in south eastern Iceland, at the head of the Breiðamerkurjökull glacier branching from the Vatnajökull, between Skaftafell National Park and Höfn, it evolved into a lagoon after the glacier started receding from the edge of the Atlantic Ocean.

Scolecite is a tectosilicate mineral belonging to the zeolite group; it is a hydrated calcium silicate. Scolecite, like natrolite and mesolite, usually occurs as acicular (needle-like) and fibrous aggregations. It has nearly the same angles between the crystal faces as does natrolite, but natrolite is orthorhombic and scolecite is monoclinic.
