"...a peak with the unofficial name of Gimli I - a very impressive peak as seen from the Slocan valley road - and unfortunately known (erroneously) to most as Gimli..." (February 1970 letter from Dean, file S.1.59). However, no subsequent use or local recognition of the name "Mount Dag". These are not challenging climbs - they require more scrambling than technical expertise; after their 1st ascent in 1963, mountaineers have seldom returned to this area, hence "Mount Dag" is not used by that community or referenced in climber's journals any more. The entrenched local name is "Gimli" and should never have been discounted by the mountaineering community, as documented by Village of Slocan Council and residents, in support of their request to change the name (1996, 1997 letters, file S.1.59).
