Rocky Mountains. Moreover, it is reported that no colours are found by panning creeks draining the east side of the Rocky Mountains in British Columbia. No mineralization is known to occur in the Plains Region east of the Rocky Mountains. The absence of known placer- and lode-gold deposits in the Rocky Mountains and Plains, together with the lack of known intrusive rocks, indicates that the part of British Columbia lying east of the Rocky Mountain Trench between Lower Post and Téte Jaune is not an attractive region for lode-gold prospecting.
