In 1983, in a course of the oeav, only HMS was used. There were no good belaying devices. Most devices are specific about rope diameter.... Most modern climbers don't know how to use the hms as belaying thing.... That's not good... Nice video! The Gran Paradiso area is interesting...
It’s the central swiss government mapping site. The equivalent to OS in the U.K. or USGS in the USA. Their site is geo.admin.ch The french version works well too, but there are similar across much of Europe and they’re very handy.
