Crooked Forest in Poland through Process of Soil Creep

The Crooked Forest (PolishKrzywy Las), is a grove of oddly-shaped pine trees located outside Nowe CzarnowoWest PomeraniaPoland.
This grove of approximately 400 pines was planted around 1930, when its location was still within the German province of Pomerania.

In a tiny corner of western Poland a forest of about 400 pine trees grow with a 90 degree bend at the base of their trunks - all bent northward. Surrounded by a larger forest of straight growing pine trees this collection of curved trees, or "Crooked Forest,"

My note: There is no mystery in the way the trunks of the tress became crooked or bent into curve for 90 degrees as they say. Here is the explanation and Illustration: because the tree is created by Nature, hence, only the process of nature can make it happen and only God can make a tree then the process can not make intervention of any mechanical device or system. 
In Geology, the process is called Creep. The illustration and explanation by the experts on these is shown below. I had a minor subject in Geology in College of Engineering that is why I was able to find the answer and also found of the same opinion/comment of who studied Geology as I tried to research. 

Soil Creep

Schematic of soil creepSoil creep is a slow process based on wetting and drying (or freezing and thawing) cycles. Its signs are subtle, but building designs must account for it.

CREEP

The slow, often imperceptible downslope movement of soil or other debris is called creep. Because creep moves materials so slowly, it is difficult to discern directly. Observation of the effects of creep, such as bent trees, tilted fences, and cracked walls, usually leads to identification of the problem.
Creep is caused by the interaction of multiple factors, but heaving is likely the most important process. Heaving involves the expansion and contraction of rock fragments, and occurs during cycles of wetting and drying, as well as freezing and thawing. As expansion occurs, particles move outward, perpendicular to the hillside. During contraction, the particles move back toward the hillside, vertically, and end up slightly downslope of where they began. The repeated motion of individual particles results in net downslope movement of the material. Areas that undergo wet/dry or freeze/thaw cycles are most susceptible to creep.
Solifluction is a special type of creep that occurs in cold regions underlain by permafrost. During the winter, the ground freezes right up to the surface. When the surface layer thaws, during the spring and early summer, the meltwater cannot percolate downward into the frozen layers beneath. This causes the surface layer of soil to become waterlogged, facilitating downslope movement as the layer becomes saturated. In this case the surface layer flows, riding above the frozen ground beneath. Although most common in permafrost areas, solifluction can occur anywhere that the surface soil layer becomes saturated.
Although movement associated with creep is slow, it causes significant economic damage because it is a widespread phenomenon that is probably occurring to some extent on virtually all soil-covered slopes. Some of the problem relates to the difficulty of detection. Unless trees, walls, or other built structures are deformed, it is difficult to impossible to determine whether or not creep is occurring. Unfortunately, where creep has been identified, it is also difficult to control. The best response to the problem is to avoid building in areas undergoing creep. Where construction is necessary, buildings should be anchored to bedrock beneath the creeping soil and debris layer.
