The day after climbing Mount AthabascaNorman Collie and his party ascended the right side of the Athabasca Glacier and bivouaced for the night. Setting off at 1:30 the next morning they headed for the chisel shaped, glacier draped mountain (Mount Columbia) they had seen towering above the opposite side of the icefield. At noon, when they seemed no closer to their goal, they turned back, more aware now of the size of the icefield they had discovered.
Collie and Hugh Stutfield later wrote, "To the eastward of where we stood, and almost on our way home, rose a great white dome, and we determined to ascend it. After a hot and very tiring climb through snow that broke under our feet at every step, we finally reached the summit at 3:15. We have named this peak The Dome."
The broad, smooth summit of what is now called the Snow Dome is the hydrographic apex of North America. This means that water from this point flows to three Oceans; through the Saskatchewan and Nelson Rivers to the Atlantic, through the Columbia to the Pacific, and through the Athabasca, and eventually the Mackenzie to the Arctic.
