PKOLS is the traditional name of Mount Douglas (2013 advice from Tsawout Hereditary Chief Eric Pelkey) Note that Pkaals [sic] was identified in 1960 by Songhees Elders Sophie Mishael and Ned Williams as the traditional name of Mount Tolmie, 4+ km south of here.

Originally known as Cedar Hill, because the cedar palisades surrounding Fort Victoria were cut here in 1843. Presumably the feature was renamed when James Douglas gave this and surrounding land to the City of Victoria (date not cited), and the descriptive "hill" changed to "mountain" as befitting a person held in such high esteem. See Governor Blanchard's dispatch in "History of British Columbia" vol I, by Howey & Scholfield, p.515. Reference to the original name still lingers in today's Cedar Hill Road and Cedar Hill Crossroad.
