The Tsõõrikmägi hill got its name from the evenly round hollow with steep brinks in the middle of the hill.

The Tsõõrikmägi meteorite crater near Räpina dates back to the period after the ice age. Scientists believe that it might be 9,500 to 10,000 years old. The circular dike of the crater is 38–40 meters in diameter.
