After going past the 'dryfall' I walked around 1km more thru the canyon.
Finally here, in the origins area, the canyon gets narrower. In the picture
it's a 90 degree bend to the right, pictured from above; the flows coming
downwards violently collide with the wall in the front which is modelled by
the waters in a concave shape. Also interesting is the layout of the
geological strata. From the place where I decided to return one could walk
for 1-2km more to the canyon end in the main ridge.
