Mount Ratz is a mountain located just west of the Stikine River, about 50NaN0 east of the British Columbia-Alaska border. It is the highest peak in the Stikine Icecap and of the Boundary Ranges which in turn form part of the Coast Mountains. It is an extremely high-prominence summit, with a difference in elevation with its "key col" at Hyland Ranch Pass of 24300NaN0.[3] Thus making it one of Canada's Ultra peaks.
Mount Ratz is named for William Francis Ratz, Dominion Land Surveyor and engineer-in-charge of surveying the Taku, Whiting and Stikine Rivers, who died on February 6, 1909.
"I regret to have to record the death of Mr. W.F. Ratz which occurred in Ottawa on February 6. Mr. Ratz had been employed on the Alaska survey since 1905. He carried out demarcation of the line at [Tsirku] river (Chilkat district), and in part between Taku Inlet and Whiting river. During the last two years he was engaged on the topographical survey between Whiting and Stikine rivers, not the least difficult section of a very difficult survey. His success in carrying this to completion in a relatively short time is a testimony of his capability as a surveyor as well as to his personal energy. His death, at the early age of 25, is a serious loss to the profession and to the public service."
