The invention relates to a method and a protection system for hindering the progress of avalanches that fall with high velocity and contain an enormous amount of energy. The method consists mainly in catching the avalanche in a special Avalanche Protection System ( 1 )-the APS-where the protection system is placed in an oblong storage box ( 16 ) on a mountain slope, in a canyon, at the foot of a mountain or at other places, where the risk of falling avalanches exists. The APS can be put up in overlapping rows to form a continuous protective wall against a potential avalanche. The protective device ( 1 ) consisting mainly of a semi-circular net sack ( 9 ) with mesh and opening; a top rope ( 13 ); a foot rope ( 10 ); leading strings ( 12, 14, 15 ) and wing units ( 7 ) attached to the top rope ( 13 ) and the net sack ( 9 ); main strings ( 3, 11 ) which are fastened to ground anchors ( 2 ) at one end and at the other end to leading strings ( 12 ), foot rope ( 10 ) and the top rope ( 13 ) of the net sack ( 9 ); flat plates ( 8 ) that are attached to the main strings ( 3 ); storage platform ( 5 ) standing on poles ( 4 ) which are equipped with locking hinges ( 6 ); and a protective helmet ( 17 ).
