The present work develops a part of the experimental works that we are carrying out in the supraforestal level of the eastern Pyrenees.The work has been accomplished AEG DVB4850B Chimney Cooker Hood - Black on an erosive level near the crest, in a limited zone of 340m2 at 2.170 m.of altitude.
The experiments attempt to detect the movility ofstones in the periglaciar micro- figurations, mainly stone circles and Curling - Stabilizers sorted stripes.Systematic observations during three years verify the fonnation of decimetric geometric figures from 2.170 m., under certain parametres (mineral fraction, gradient, vegetal cover, frost-thawing cycles, etc.
).
