Hydrological natural heritage
Interesting hydrological natural heritage is preserved by the Zaganjalka or Zaganjalščica spring under the village of Cerkljanski Vrh in the Volkova Grapa ravine near the Zakrog farm. The spring is located high below the Lajše hill and its water flows into the Idrijca river below the section of the Cerkno-Idrija road near Želin, known by locals as “Pirhov Klanec”. This is an interesting karstic phenomenon, for which a change in water flow is characteristic. The water dries and rises again in regular intervals, almost as in jolting movements. At regular flow it takes seven minutes before the water almost disappears and then gushes out of the depths again.
All other such springs are named after Zaganjalka in the Cerkno region in Slovene terminology.
Here you can see an interesting video of how Zaganjalka functions.
