The Rodenbeker Quellental nature reserve is an 84-hectare glacial meltwater river system in northeast Hamburg. It lies in the former edge area of the Vistula glaciation. Locally there are elevations in the form of ground moraines. The site elevation is between 15 and 20 meters above mean sea level. The site was granted protected status on January 25, 1977, originally measuring 47 hectares. On July 26, 2011, the Hamburg Senate announced an expansion by 37 hectares to 84 hectares. In the Quellental there are extensive deposits from an ice reservoir, which are now cut through by various smaller basins, small rivers. These are the Rodenbek, the Bredenbek, the Lottbek, the Mühlenbek and other small streams. All flow in an east-west direction to the Alster, a northern tributary of the Elbe. The formation of the Rodenbeker Quellental began in the Weichselian Ice Age, when the Bredenbek Glacier slowly retreated and the meltwater at the base of the glacier found its way to the Alster. The current appearance of the spring valley is also due to spring erosion. (Source: Wikipedia)
