The Silverthrone Group is bounded in the east by the Klinaklini and North Klinaklini rivers, in the south by Knight Inlet, in the west by the Pacific Ocean and in the north by Owikeno Lake, Rivers Inlet and the Sheemahant River. Climbing and explorations of the group began in at least 1900; some of the mountaineers involved in these activities were Don Munday, Phyllis Munday and John Clarke.

Names and etymology

This mountain group has been called the Silverthrone Group by the British Columbia Mountaineering Club and the Silverthrone Cluster by the Bivouac Mountain Encyclopedia. Such terms are derived from Silverthrone Mountain, the highest point of the Silverthrone Group whose name has been reported in Canadian Alpine Journal articles as early as 1933. Silverthrone is descriptive of the icy landscape; it may have been coined by Don Munday who carried out the first ascent of Silverthrone Mountain along with his wife Phyllis Munday in 1936.
