Arthur Oliver Wheeler [1860–1945] led the Alpine Club of Canada–Smithsonian Robson Expedition in 1911:

The glacier up which we had travelled, leading to the snow-filled cirque south of Mt. Gendarme, is of much interest; the ice is thickly veneered with stones and is strewn with glacier tables, and with numerous perfectly formed sand-cones, reaching a height of five feet. Most striking, however, is a great ice wall, 400 feet high, that separates the neve from the dry glacier and reaches right across it. The moving ice-field above flows over this cliff and sends down fragments to litter the floor of the glacier below. It is referred to here as the “Mural Glacier.” [1]

Paleontologist and geologist Charles Doolittle Walcott [1850–1927] explored in the area in 1912:

A new fossil find was made by chance. Mr. Harry Blagden and I were sitting on a huge block of rock at the lower end of Mural Glacier, munching our cold luncheon, when I happened to notice a block of black, shaly rock lying on the ice. Wishing to warm up, for the mist drifting over the ice was cold and wet, I crossed to the block and split it open. On the parting there were several entire trilobites belonging to new species of a new subfauna of the Lower Cambrian fauna.[2]
