Definition: Asymmetric Valleys form due to the aspect driven sun exposure and thermal erosion. The cold slopes are the steepest, whereas warmer slopes typically experience more freeze-thaw cycles, hence weathering and Solifluction / Gelifluction processes. The asymmetry depends on the hemisphere. In the Southern hemisphere, south facing slopes are colder. In the cold environments of the Andeas one can distinguish between: 1. Valles unregularly bottomed 2. V-shaped valleys 3. Flat-bottomed, or U-shaped valleys  TrombottoGeocryology
