The Seven Sisters had attracted the attention of Dr. J. Monroe Thorington (1916), Henry S. Hall Jr (1923 and 1938) and Allen Carpe (American Alpine Journal, vol 1, p.425.); Hall has described the Seven Sisters as "...so shaped and situated as to be easily the outstanding sight west of Mount Robson." (American Alpine Journal vol IV (1), p.142.) From: "A First Ascent in the Seven Sisters Range" by Neal M. Carter, Canadian Alpine Journal vol. XXVIII, no. 1, 1941, pp.88-100, including map and photographs.
