Deltaform Mountain is the highest of the "Ten Peaks." Originally named Saknowa by Samuel Allen, it was renamed Deltaform Mountain by Walter Wilcox in 1897 after he was impressed with the peak's similarity to the Greek letter "Delta." The summit cliffs feature a horizontal band of light-coloured rock just below a dark coloured band near the summit.
