"...from the centre of the plateau rises the great ice-covered mass of Edziza Mountain. Edziza means in Tahltan "sand" and it is from the deep deposits of volcanic ashes or pumiceous sand which cover large strips of the plateau that the mountain takes its name." (1927 report by J. Davidson, BCLS, published in Abtracts of BC Land Surveyors Reports, Cassiar Dist, p.185). Edziza means "cinders" in the Tahltan dialect (BC Parks brochure). Edziza is an extinct volcano; its' name means "red sand" referring to the red lava dust on it. (1933 advice from P.M.Monckton, BCLS). Note that David Stevenson, University of Victoria Anthropology Dept advised in October 1970 that "kutlves" is actually the Tahltan word for sand or dust.

Many years ago Johnny Edzerza, his wife Eve, and a Mr. Hank Williams were crossing [this mountain] when an avalanche killed both men. Johnny Edzerza was buried on the mountain but his grave marker was mis-spelled 'Edzertza'. Dr. J.G. Souther, Geological Survey of Canada, later named Eve Cone after Eve Edzerza, who was still living in the area; Souther further suggests that Edziza is a corruption of Edzerza, although he does not necessarily link the avalanche event to the original naming of the mountain. (20 December 1974 telephone conversation with Dr.Souther; transcript on file T.2.54). The Edzerza family continued to live in the area through the war years and since, according to G.S. Andrews, BC Surveyor-General. One Arnold C. Edzerza is listed as an Atlin-based big game guide in the 1974 Directory.
