"Sinyushka's Well" (Russian: Синюшкин колодец, tr. Sinjushkin kolodets; lit. "Sinyushka's Water Well"), also known as "The Blue Crone's Spring" and "The Blue Baba of the Marsh", is a folk tale (the so-called skaz) of the Ural region of Siberia collected and reworked by Pavel Bazhov. It was first published in the Moscow Almanac in 1939 (pp. 256–266). It was later included in The Malachite Casket collection. "Sinyushka's Well" is one of the most famous stories in the collection and is still popular nowadays. The story was translated from Russian into English by Alan Moray Williams in 1944, and by Eve Manning in the 1950s.
