Origin of the name unknown.

The mileage does not in this case refer to the distance from the Yellowhead Pass along the railway.

W. S. Fetherstonhaugh, a divisional engineer with the Canadian Northern Railway in Calgary, surveyed in the area in 1906 and 1907. The feature was named by the Alberta-British Columbia Boundary Commission in 1923.

In October [1924], discussions [the Geographic Board of Canada] started regarding new names for the mountains on which the Geodetic Survey established stations. The mountain on which Lambart had a station named for his son, Arthur, was changed to Going Mountain, named for a Grand Trunk Pacific engineer who had worked in the area. Then it was changed to Fetherstonhaugh, named for another railway engineer who had worked in the area. Arthur soon received a third name change. “As Arthur peak is more outstanding than Boyd the Board would prefer that the name Côté [a senator from Edmonton] be applied to it and the name Fetherstonhaugh be transferred to Boyd.” A nearby pass was also named Fetherstonhaugh.

Howard Frederick John Lambart [1880–1946], Dominion Land Surveyor, was head of the survey of the Jasper National Park North Boundary.

The 1911 Alpine Club of Canada–Smithsonian Robson Expedition was led by Arthur Oliver Wheeler [1860–1945]. On the Robson River below Emperor Falls, Wheeler in described “a second big fall of 150 feet. It suggests the name of the ‘Fall of the Pool.’ Two-thirds of the way down is a tiny pool in the rock into which the water leaps; the lower part is more broken.”

In 1917, while serving in the Canadan Army Medical Corps in France, George R. B. Kinney [1872–1961] wrote to Arthur Hinks, the secretary of the Royal Geographical Society in London, that he would be pleased to deliver a lecture on mountaineering in the Canadian Rockies, illustrated by “100 choice colored lantern slides, second to none (by report), and taken from my own negatives.… Mine are the original photographs taken of these hither to unexplored regions, and names like ‘Berg Lake,’ ‘Tumbling Glacier,’ ‘Robson Glacier,’ ‘Mt. Rearguard,’ ‘the Helmet,’ and ‘the Extinguisher’ that now have a permanency, were my suggestions, while Dr. Coleman gave the name of Lake Kinney on Mt. Robson’s western foot.” [1] Kinney delivered the lecture in January 1919, and was subsequently elected a Fellow of the RGS.

Kinney had accompanied Arthur Philemon Coleman [1852–1939] and Coleman’s brother Lucius on the first mountaineering expedition to Mount Robson in 1907, when they approached from the Fraser River side and got little further than Kinney Lake. They returned in 1908, guided by Adolphus Moberly [1887– ?] and John Yates [1880– ?], who took them up the Moose River valley and approached Robson from the north. They became the first people to report on Berg Lake, Tumbling Glacier, Robson Glacier, Rearguard Mountain, The Helmet, and Extinguisher Tower, features Kinney named after their appearances.

“At a bold tower of rock, which had been nicknamed the Extinguisher, the Robson glacier widens out and bends nearly at a right angle toward the main peak,” wrote Coleman. [2]

Smithsonian Institution director Charles Doolittle Walcott [1850–1927] called it the most valuable spot in the Rockies to geologists. “One of the names proposed by Dr. Coleman for a prominent monadnock that is surrounded by ice, east of Mount Robson, is ‘The Extinguisher’ and Mr. Wheeler has adopted the name on his map. I presume Dr. Coleman had in mind the conical extinguisher used in putting out candles in the olden times. It so happens that that particular mass of rock carries a very important bed of Cambro-Ordovician fossils, and will be referred to many times in the future in literature. It may be that I shall suggest a shorter and more euphonious name for it,” Walcott wrote to the Surveyor-General in 1912. [3]

His suggestion, “Billings Butte”, was not adopted. Walcott was referring to Arthur Oliver Wheeler [1860–1945].

“On the cirque immediately below Mount Resplendent stands a quaint tower of rock some 500 feet above the ice, named the Extinguisher from its likeness to the conical cap once used to put out the candle,” wrote Elizabeth Parker [1856–1944], a member of the Alpine Club of Canada’s 1913 camp at Robson Pass.

Everett Creek adopted in the 1930 BC Gazetteer, as labelled on a BC Lands’ map of 1923, not “East Fork Slim Creek” as identified on earlier maps.

One of the peaks of Mount Lyell, named for Swiss guide Ernest Feuz (1889-1972), a mountain guide for the Canadian Pacific Railway. He was the son of Edward Feuz Sr. and brother of Edward Feuz Jr.

Ernst Feuz came to Canada in 1909 and guided at Glacier House until 1925, when he was transferred to Lake Louise. The Feuz family lived at Golden, B.C.

The peaks on Mount Lyell include Rudolph Peak, Edward Peak, Ernest Peak, Walter Peak and Christian Peak (Canadian Permanent Committee on Geographical Names, 1972).

The name commemorates fur trader Edward Ermatinger (1797–1876), who was born on the Mediterranean island of Elba where his father was employed by the British Army. Ermatinger was educated in England, and in 1818 apprenticed to Hudson’s Bay Company . In 1825 he was posted to the Columbia Department, which then included New Caledonia. He remained in the service of the HBC for ten years, and in 1830 retired to St. Thomas, Upper Canada.
