Above the main valley of Chosica are various active debris flow areas. Some are subject to further land speculation, as this unreal choice for a new hut shows. Some have been protected unsuccessfully, as seen in the broken through barrier. And some are being protected again, for example with this ring net from Geobrugg in Switzerland, hopefully with more success.
