Zircons from the Westcoast Crystalline Complex near Tofino, Vancouver Island, have yielded the following ages: 206Pb/238U = 265 ± 7 m.y.; 207Pb/235U = 263 ± 7 m.y.; and 206Pb/207Pb = 244 ± 20 m.y. A K–Ar date of an amphibolized dike from the same outcrop yielded 192 ± 9 m.y. This is the first supporting isotopic evidence that the 'basement' complex is derived from late Paleozoic Sicker volcanic rocks and was ultimately migmatized during the major Jurassic plutonic event of Vancouver Island.

Thirty-one species of eutardigrades were collected on five mountains on Vancouver Island, British Columbia, during July 1986 and July 1987. Three of the species found were new to science, including 1 species, Platicrista cheleusis n.sp., described herein and 2 species described elsewhere, and 21 others are new to British Columbia; 13 of these are also new to Canada.
