Kurisu küla, Hiiumaa vald, Hiiu maakond
Kurisu sinkhole is located near Kurisu village.
The upper part of the sinkhole has a diameter of about 32 metres, in the lower part it narrows down to 12 metres, and it is 6.2 metres deep. In here, the creek coming from Pihla wetland disappears under the ground.
In summer, when the weather is dry, you can see a limestone bedrock and a little opening to a cave at the bottom of the sinkhole. During high water in spring, so much surface water gathers here that the crater is filled with it and some of it spills over to the surroundings so that the whole place is reminiscent of a little lake.
The water that disappears into the sinkhole re-surfaces on the ground 3 km away on an old pasture in Pihla village.
