Additional note from Gerald Barnes: "Champion Mine on the Cottage Grove Ranger District, Umpqua National Forest is ‘famous’ as site of first finding of very high genetic resistance to white pine blister rust (WPBR) – turned out to be ‘major gene resistance’ – written up many years later (Kinloch et al. 1999, Phytopathology)."
