What is canyoning.
Canyoning is one of new sports of last decade. It is the crossing of
gorges following the course of waters and overtaking each obstacle with
technical means. That is to say, the descent of canyon walking through
water, making plunges in deep waters, natural slides that have been
shaped above in the rocks by the erosion of waters and descent with
ropes, when it has waterfalls. The terminology Canyoning in the Greek,
translated as crossing of canyons. Canyoning  contains mountaineering,
ascension, speleology, swimming. It is a sport that combines many
mountain sports!
What is canyon? 
Canyons are a geological particularity. Most of them were created the last 10.000.000 years and they are result of geological changes that is owed in the seismic and volcanic activity. At the duration of Tetartogenis period (the last 1.500.000 years), the alternate icy and middle-icy environments and the geodynamic activities, caused the fast ascendant movements of ground, where in combination with the tektonokarstical phenomena, they created favorable conditions for intense erosion. Result of all these were the deep canyons. The humid element is also an important factor of creation of canyons. The enormous quantities of water that were released at the melting the glaciers, following the various ways of cracks, sculpture deeply the limestone mainly rocks, giving the bas-relief of canyons.
Canyons are small mountainous rivers with permanent or seasonal flow, having a basin of catering. Their bent usually is bigger the 5% and is found in the phase of permanent erosion. From a basin of catering and when the water at his course passes above hard rocks without meets some deep crack, then the canyon that is created is not enough deep. Many of these canyons can be distinguished from far, but they are equally beautiful and impressive!

Rocks of canyon are not essential through all its length. There exists much different morphology because the quality of rocks is alternate. It is interesting often to know also, various elements for the water wagon horizons where they influence and the output of waters in the canyon. Rocks are characterized by a line of natural attributes, from which most basic is their cruelty, which involves smaller or bigger resistance in the erosion of water. Paradoxically, the bigger the cruelty of rock is the bigger narrow and vertical is the canyons. Rocks with softer shape only canyons with big opening form V to above.  
We are reported in waters of snows and rains that fall in ' ' basin '' (undergrounds lake of feed-in) and coming out from the sources cause a mechanic erosive action where with the dissolution of salts of carbonic acid, is created also a chemical reaction which is also this one from the causes of erosion. The action of solvents produces the various forms cortical, surface or undergrounds.
