 Over the next decade, the Mundays mounted several expeditions into the area in an attempt to climb the mountain.Known to them as "The Mystery Mountain", in 1927 the height was measured at 13,260 feet (by triangulation), and the Canadian Geographic Board gave it the name Mount Waddington after Alfred Waddington who was a proponent of a railway through the Homathko River valley.They reached the lower northwest summit in 1928, deeming the main summit too risky.
