Actually, the early mountain men here in BC, did not wear mocassins and did wear highend, custom made boots. The terrain is such that moccassins are pretty much useless and BC was largely explored during "The Victorian Era" when climbing boots were first developed in the European Alps and then brought here.

Buckskin was also not often used in BC, the explorers here wore woolen, some cotton (linen) and leather garments and not hides,etc.
