To combat the SPAM and the VIRUS that have invaded your mailbox, we do not deliberately put in our e-mails any link other than to our site.

The advantage of a Web site in relation to a printed handbook is that it can evolve on demand. In order to adapt to any expectations, it would be invaluable to know in which category of visitorswho were interested in the site do you belong, what you liked most about it, or what youdid not find, etc …

If you send a message , even very brief, we are interested in whether you are “simple curious”, “amateur tourist”, “enlightened hiker”, “student”, “professor of geology”, etc …

Any suggestions are welcome to improve the content and accessibility of this site, as well as its interest in the various categories of visitors possible .

All indications about the navigation and layout bugs (or even typos) are also greeted with gratitude .

Thank you for your messages!
