Staburadze
Staburags or Staburadze was an unusual 18-meter (59 ft) high cliff on the bank of the Daugava River in Latvia shaped and formed by lime-rich springs. According to a legend, it was once a girl in mourning who was petrified.
Since 1965, the cliff has been submerged at a depth of 6.5 meters (21 ft) due to the construction of the Pļaviņas Hydroelectric Power Station dam.
