A ravine in Kolomenskoye that Moscow tells stories about as a place where time comes loose. In the best-known version, a detachment of Tatar horsemen vanished into it during Devlet Giray's raid of 1571 — and in 1621 riders in antique armour appeared at the tsar's gates. Questioned, they insisted they had gone down into the ravine to escape pursuit, hidden in a greenish fog on its floor, and stepped out of it a few minutes later. Fifty years had passed. Two enormous boulders lie at the bottom, the Goose and the Maiden Stone; people still come to make wishes on them, and the fog really does linger there longer than on the slopes.
