Karjaoru Falls

Karjaoru Falls (Karjaoru joastik or Karjaoru juga) is a waterfall in northern Estonia. It is located in the village of Saka in Toila Parish, Ida-Viru County.

The water of the falls comes from the main channel of Ontika Creek, a drainage ditch. There are two escarpments on the stream; the height of the first one in the direction of the flow is 3.5 m and the second one is 5.5 m. In total, the total height of the cascades is 12 meters. After the escarpments, the water continues to flow down, creating a waterfall with a total height of 18 m. The water in the channel is low only in very dry summers.

The outcrop at the falls is a stratotype of the Saka Member of the Toila Formation. The upper 6 m are made of limestone (Loobu Formation and Aseri Formation). Below it is a 15 cm layer of clayey ooid-containing limestone of the Silaoru Formation. Below it is a 130 cm layer of glauconite-containing limestone of the Kalvi and Künnapõhja Members, and the lower part of the outcrop consists of thick-layered yellow dolomitized limestone of the Saka Member.
