The post was known as Campbell's Fort, in honour of its ill-fated former factor, Robert Campbell.
Harper hired J.J. "Buffalo" Pitts as his assistant, and it was Pitts who stayed on to run the operation when Harper left four years later to found his last post at Ogilvie with Joe Ladue. In 1897, some of the first stampeders stopped at Fort Selkirk, only to find that no steamer had delivered supplies since 1895. Pitts had nothing to sell them except condensed milk at a dollar a tin.
