Giscome Portage
Leading from the Parsnip River to the Fraser, in
northern British Columbia. Named by an independent trader, Peter
Dunlevy, after his cook, about the year 1873. Both Mackenzie and Simon
Fraser crossed from the Parsnip to the Fraser, the former in 1793, and
the latter in 1806, but neither went by way of Giscome Portage, which
was not discovered until some years later. =Bib.=: Burpee, Search for
