The area is described on Wikipedia as follows:

It is not so far north as its extreme Arctic-like conditions might indicate and Mount Waddington and its attendant peaks pose some of the most serious expedition mountaineering to be had in North America — and some of the most extreme relief and spectacular mountain scenery.

From Waddington's 13,186 ft fang to sea level at the heads of Bute and Knight Inlets is only a few miles; across the 10,000-foot-deep (3,000 m) gorges of the Homathko and theKlinaklini Rivers stand mountains almost as high, and icefields even vaster and whiter, only a few aerial miles away, with a maw deeper than the Grand Canyon, comparable in relief to the Himalayas (to which the terrain of British Columbia was compared by colonial-era travellers).

A fascinating remote area, and only 270km as the crow flies from Vancouver.
