It is an enclosed depression around the great heights, partially wooded. The most remarkable in this meadow is the water loss system, which is made in the bedrock of the river through strainers. During low waters there are two active strainers.
During heavy waters caused by persistent rainfall or snowmelt, these strainers can not drain all the water that accumulates, exceeding the normal bed of the river. As the water rises and floods usually dry areas, new strainers become active.
When these new ones can not drain the water, the entire meadow is occupied by the waters of a lake. The additional waters of the lake are discharged through the north-west of the clearing over a rocky threshold, giving birth to a violent torrent flowing to Fortresses Valley.
