The Island White quarry is located 1 kilometre northeast of Squamish, 150 metres east of the old Whistler Highway.

The area, in the vicinity of Squamish at the head of Howe Sound, is underlain by Cretaceous granite and granodiorite of the Jurassic to Tertiary Coast Plutonic Complex.

The stone from this quarry consists of a medium to coarse grained equigranular granite comprising up to 10 per cent black biotite and 30 to 40 per cent grey quartz in a milky white feldspar matrix. The rock is very similar to the granite at the Marchesi Granite quarry (092JNE144), but is slightly coarser in grain size.

Island White Quarry Corporation is producing granite on a seasonal basis from this quarry. A total of 350 tonnes were quarried in 1990, the first year of operation (J. Grinnell, personal communication, 1991). The granite is shipped to the processing plant of Pacific Granistone Corporation in Delta, where it is cut into panels suitable for such uses as building facings and paving stones. The stone is marketed under the name "Island White Granite." A new (1996) plant in Squamish, operated by Garibaldi Granite and Pender Capital Corporation, will process stone from this quarry. Pender Capital acquired 100 per cent of all Granigroupe Inc.'s (Quebec) assets including Grabaldi Granite in 1999.

The front of the Customs and Immigration Building (1914) on Government Street in Victoria has a base of Island White granite.

Garibaldi Granite Inc. currently markets Glacier White from this quarry.
