"Mission Mountain" described in Geological Survey summary report 1918, part B, p.25, and in reports by G.M. Downton 1913-23, as overlooking Shalalth or above Seton Lake (ie. extent not clear). Long time residents Bert Williams, Elliott Hanson and Benjamin Peter, who accompanied Major F.V. Longstaff on his 1930-31 survey and explorations of the area, indicated that the namesake Mission was situated "...in the Indian Reserve of Shalalth on the north shore of Seton Lake, where a stream comes down from Mission Mountain..." (because numerous streams flow off the ridge all along the length of Seton Lake, the implication is that "Mission Mountain" refers to the single mountain with a prominant triple-summit above Shalalth. This mountain is on the east side of Mission Pass). Elsewhere however, Longstaff was told that "Mission Mountain" extends from the portage between Anderson and Seton Lakes (ie. Seton portage) to about half way along the north shore of Seton Lake - a distance of some 10 miles. The description provided by Benjamin Peter: "...high open timber land with good grazing for the many Indian horses which live here" applies either way. "It would appear from our earliest reference that this geographical feature has been known as Mission mountain or mountains. Requirement has arisen to fix a permanent naming to the feature east of Mission Pass and it is thought the best naming would be Mission Ridge, because the type of the feature is more of a ridge formation than peak, mountain or mountains. We already have a Mission mountain recorded, on the Tsimpsean peninsula." (14 December 1931 letter from BC Geographic Division to E.C. Carpenter, BC Electric Railway, file L.1.38).
