Deltaform Mountain, Mountain summit at Continental Divide, Alberta and British Columbia, Canada
Deltaform Mountain is a peak on the Continental Divide between Alberta and British Columbia, Canada, rising above 3,400 meters (11,155 feet). It sits in high alpine terrain between Banff and Yoho national parks, where steep rock faces and narrow ridges define its shape on all sides.
The peak was named Deltaform in 1897 by Walter Wilcox, who replaced the earlier name Saknowa given by Samuel Allen. Both men were among the early explorers mapping the Canadian Rockies during a period when many summits in the region had not yet been officially recorded.
Deltaform Mountain sits at the edge of the Valley of the Ten Peaks, a row of summits that has appeared on photographs and posters of the Canadian Rockies for generations. The valley below is visible from Moraine Lake and draws many visitors who come to take in the view from ground level.
Reaching the summit requires technical climbing experience, as the terrain is steep and demanding throughout. Mid to late summer offers the most manageable snow and ice conditions, though weather at this elevation can shift quickly and without warning.
The name Deltaform comes from the shape of the peak as seen from below, which resembles the Greek letter delta. This triangular outline is clearly visible from Moraine Lake, and it is likely what led Wilcox to choose that particular name.
