The Blue Eye, the Spring with No Bottom
In the hills of southern Albania, a pool of startling blue water looks like an eye. Divers have gone down more than 50 metres and still haven't found the bottom.
What was reported
Syri i Kaltër, 'the Blue Eye', is a spring in southern Albania where water wells up from a deep hole in the rock. In the middle it's a dark, deep blue, ringed with paler turquoise, so from above it looks like an iris.
It was long said to be bottomless. Divers have gone down more than 50 metres into its shaft without reaching the end, and the water, always cold, never seems to stop.
Explanations offered
The Blue Eye is a karst spring: rain and snowmelt soak into the limestone mountains and travel through underground channels, pushing up here under pressure. Its full depth is still unknown because the narrow shaft and strong current make deeper dives very hard.
