The OHM is a free service, open to all, all year round. It is an associative structure depending on the "Chamoniarde" : mountain prevention and rescue society.
The Office de Haute Montagne was founded in 1972 by the Chamonix guide Gérard Devouassoux. After a particularly worrying mountaineering season, public opinion was moved to seek a solution that would preserve freedom while limiting and reducing mountain accidents. The Office de Haute-Montagne was therefore born from the generous, original and effective concept of tackling the delicate issue of mountain accident prevention through information. The practice of the mountain does not accept administrative constraints, the mountain must remain a space of freedom.
