Named in 1863 by Viscount Milton, after his companion Dr. Walter Butler Cheadle (1835-1910); they travelled this way on their journey to the Pacific Ocean. "...we came in sight of a fine snowy mountain which appeared to block up the valley ahead, and we hoped this might be the second of the two described to us as landmarks by the old woman at the Cache, which she stated was not far from Fort Kamloops." [journal entry 1 August 1863]. To this Milton gave the name of Mount Cheadle in return for the compliment previously paid him... (The North-West Passage by Land, 1864, 5th edition, p.290 )

Cheadle was born in 1835. He was educated in Bingley Grammar School and Caius College, Cambridge, at which college he held a scholarship. In his younger days he won some distinction as an athlete. Died 25 March 1910. In June 1862 Milton and Cheadle undertook an expedition across British North America. As stated in the preface to the first edition of "The North-West Passage by Land" it was 'undertaken with the design of discovering the most direct route through British territory to the gold regions of Cariboo, and exploring the unknown country.... in the neighbourhood of the sources of the north branch of the Thompson River.' The narrative of the expedition was published in June 1865 under the title "The North-West Passage by Land" [identifying Viscount Milton and Dr. Cheadle as co-authors].... a careful reading of the journal demonstrates that Cheadle was the author and that Milton had no substantial claim to joint authorship. It has been described as one of the most vivid and picturesque accounts of travel ever written.... ran through 5 editions in eight months, the 9th edition appearing in 1901. ("Cheadle's Journal" by James White, Canadian Alpine Journal, vol XIV, 1924, p.90).

W.B. Cheadle .... the English physician who travelled this way in 1863 with Viscount Milton during their overland journey to the Pacific. Like many other travellers through British Columbia, they found little or no game down in the river valleys in summer and almost died from hunger before they reached the HBC fort at Kamloops.
