Gremyachy Klyuch is a historical stream that once flowed along the bottom of one of the ravines of the The Dyatlov Mountains in the upland part of Nizhny Novgorod. It belongs to the category of minor watercourses that have been largely hidden or lost in the course of the city's development.
Location and natural conditions
The stream ran along the bottom of an old ravine on the slopes of the Dyatlov Hills, which rise 80–120 meters above the Oka. Together with neighboring watercourses — Starkovka) and Bezymyanny Spring)) — Gremyachy Klyuch formed the drainage network of the Bolshiye Ovragi (Great Ravines) district, which stretch from the river hundreds of meters into the interior of the highland plateau. The steep, dissected terrain made this area difficult to develop: city streets in the Bolshiye Ovragi district appeared considerably later than in other parts of historic Nizhny.
Connection to local toponymy and the history of landslides
The name "Gremyachy" (from Russian "гремячий," roughly "the roaring/rumbling one") is tied to local toponymic tradition. According to one version, the word "гремячая" was applied to a hill that "rumbled" during landslides: historical descriptions of the Nizhny Novgorod escarpment mention an enormous landslide on the stretch from the former Railway Station (Vokzal) to the start of Rozhdestvenskaya, when a mass of earth, forest, and buildings came crashing down with a terrible roar onto the settlement below and wiped it off the face of the earth. The stream, the ravine, and adjacent features — Gremyachaya Gora (Roaring Hill), Gremyachy Lane — form a single toponymic cluster derived from the same root.
