The multi-tiered waterfalls and submerged tufa of Krka National Park shine in Croatia’s mid-morning sun.

The dramatic waterfalls of Krka National Park, Croatia, cascade down a travertine canyon – the largest such formation in Europe. The beautiful formations you can see under the water look like rocks or moss, but are actually tufa. Tufa is an iconic part of some mineral springs, like Mono Lake, but also forms in some rivers. When a river lacks organic content and has supersaturation in calcite, the turbulence of the waterfall can trigger precipitation onto moss or algae. It is said to be a good building material, but the tufa in Krka is now protected from removal. I’m glad for that, because it sure did add a beautiful uniqueness to this famous waterfall.
