Association with Upright Mountain.

From a camp near Moose Pass during the 1911 Alpine Club of Canada–Smithsonian Robson Expedition, Arthur Oliver Wheeler [1860–1945] noted “a high peak, which, owing to the rock strata of which it is composed having been tilted to an almost vertical angle, has been named ‘Mt. Upright’.”

Origin of the name unknown.

Named because of its proximity to the Twins.

A turret is a small tower. The feature was named by the Alberta-British Columbia Boundary Commission in 1921.

Origin of the name unknown.

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.

“From the elevated ice-field, fed by avalanching snows from the sides of Robson, a gigantic ice cascade tumbles down rock precipices and buries its nose in the waters of Berg Lake,” wrote Arthur Oliver Wheeler [1860–1945] after his 1911 visit. “At frequent intervals great chunks of ice break off with a report like cannon, and, bounding and rattling down the steep incline, plunge into the clear water of the lake. Dr. Coleman has named the overhanging ice-fall ‘The Blue Glacier,’ The term is not strong enough: ‘Tumbling Glacier,’ though not so euphonious, is a better name to express the activity of such a unique feature.” [2]

“Blue Glacier is a wonderful stream of slipping, sheering, blue, green, and white ice. Why it does not slip and slide as a whole down into Berg Lake is one of the unsolved secrets of this great mountain,” wrote Charles Doolittle Walcott [1850–1927] in his report on the 1912 Smithsonian expedition to Mount Robson.

The creek where George Monroe decided to homestead as he rafted down the Fraser in 1914 has “always been called Tumbledick,” according to his daughter Sadie Frye. The name appears on the 1915 Provincial Pre-emptor’s map. “Near the creek was Ralph Veale’s little white cabin, made of boards when most houses were made of logs.”

The stream flowing southwest through Lot 5341 into the Fraser River is labelled “Tumbledick Creek” on BC map 3H, Tete Jaune, from 1914 to 1958. The main channel has since been re-named “Monroe Creek” and the name “Tumbledick” assigned to a tributary on the north side. Large scale air photos indicate that the mid-channel of Monroe Creek has been diverted by road construction in the vicinity of Lot 9315 and now flows south into the Fraser River; Tumbledick Creek now appears to flow directly into the Fraser River via the original channel through Lot 5341.

During the 1911 Alpine Club of Canada–Smithsonian Robson Expedition, the exploratory party of Arthur Oliver Wheeler [1860–1945] climbed “the high rock buttresses that stood out prominently behind our camp to the northwest. The station was a low one, but commanded fine views up the valley of Moose River and of the valleys surrounding the Colonel. The station was named ‘Trios’ on account of its shape.”

Topographic Survey of Canada advises “the origin of the name is obviously that it has three peaks.”
