Pegmatites were exposed on a trail a short distance from the Canadian Pacific Railway. The trail (apparently obliterated by a logging road) follows Woolsey (Silver) Creek and leads to the Snowflake occurrence (082N 003).

The Woolsey Creek showing area is underlain by Lower Paleozoic quartzites, orthogneiss and quartz mica schists cut by Devonian granite-gneiss, granite and pegmatite. "Gunning found beryl in some of the pegmatites". Little or no tourmaline was evident (Geological Survey of Canada Economic Geology No. 23, page 61).
