Nice article.

This is the bit where the queen charlotte islands rift comes onland at the point where it is overridden by the North American plate and becomes an onland rift all the way up to Mt. Edziza.

One arm of the rift is the queen charlotte islands & Haider Gwaii, the other arm of the rift is the NW, part of vancouver island. Both of the outer arms are bounded on the Pacific side by megathrusts.

The Behm canal bit of the rift is notable for a large airfall tuff from an unknown volcano. This pretty pic may show the progenitor cone.

The megathrusts bounding the outer rift arms are also interesting for a different reason. The last megathrust case both in the Garibaldi arc (BC) and the E.Alaska coast (Haider Gwaii, Canada & NW into alaska) last produced a magnitude 9 in the early part of the Holocene or latest Pleistocene and bound backarc basins capable of producing large runout values and large tsunami runup values.

Have a nice day: Ag
