 For a time, official maps of the area duly recorded the name as "Carnarvon" but almost all newspapers and diaries referred to it as Harrisonmouth.In just a few weeks, during the Fraser Canyon Gold Rush of 1858, 30,000 men travelled up the Fraser River to the Fraser Canyon, upstream from Hope.Many stopped along the way, with sandbars along the Fraser near Harrison Mills and throughout the Fraser Valley turned over by prospectors.
