I still have my pb Burl Ives Songbook, Al. Falling to pieces but still regularly refd to ~~ the last time just 3 days ago, when the question of 'piker' as originally a name for a 49-er from Pike County Missouri arose in Quinion's World Wide Words & led me there to look up Sweet Betsy From Pike, which is of course a GoldRush song [note the 'miner' in the last verse] tho Ives does not specify this.
