Etymology

Seven Sisters Mountain was the name adopted in 1948, but the mountain's toponym was changed and officially adopted October 4, 1951, by the Geographical Names Board of Canada.^[3]

The individually named peaks of the massif from west to east are Tlooki Peak, Weeskinisht Peak, Tagai Peak, Tingi Peak, Kitshin Peak, Kletoosho Peak, and Tuatoosho Peak, which are the Tsimshian/Gitxsan words for One, "Top of the Mountain", Three, Four, Five, Six, and Seven, respectively. With the exception of Weeskinisht, the other names were submitted by Neal M. Carter of the Alpine Club of Canada and officially adopted in 1977.^[6]
