Hi greg. It can be difficult getting in touch with us nogs this way
Try searching up some groups on facebook, and get in touch with DNT (DNT Fjellsport Oslo og Omegn would be your local). Also, there is www.fjellforum.no which is a much more active forum than this.
There is a guidebook for hemsedal: http://sportsnett.no/s/p.aspx?pid=1828&cid=300
and a book for Sogndal is at the printers: http://friflyt.no/Ski/Toppturbibelen-for-Sogn
Good luck and have a great winter
