Over the next decade, the Mundays mounted several expeditions into the area in an attempt to climb it. Known to them as "The Mystery Mountain", in 1927 the height was measured at 13,260 feet by triangulation; they reached the lower summit in 1928, deeming the main summit too risky. On their recommendation the Geographical Names Board of Canada gave it the name Mount Waddington after Alfred Waddington who was a proponent of a road route, known as Waddington's Road, and again later the same for a railway, via the Homathko River valley and Bute Inlet, which would connect to Vancouver Island via Seymour Narrows.
