Wearing his bathing costume, a young adventurer clambers over rocks in the Gross Enz river in Germany's Black Forest. The lad of 10 crouches to better balance himself, carefully placing his bare feet on the slippery rock's surface as he emerges from the chilly mountain water. It is high summer and we can see the boy backlit by the glare of strong sunlight in the background. The Gross Enz river rises in Enzklosterle in Baden-Württemberg and is an eventual tributary of the Neckar. Geologically, the Black Forest consists of a cover of sandstone on top of a core of gneiss. During the last glacial period, the Würm glaciation, the Black Forest was covered by glaciers.
