The basal beds’ seen on Pink Mountain are quite” different from those exposed on Sikanni River. On Pink Mountain, just north of Halfway River, the base of the group is marked by a coal seam over 5 feet thick, which is overlain by 140 feet of fine- grained, dark grey sandstone interbedded with dark grey and carbon- aceous shale. These beds resemble the Kootenay formation in the Foothills of southern Alberta, and are overlain by coarse-grainec, quartzitic, sandstone’ beds with conglomerate and scattered -pebbhles of chert, quartzite, limestone, altered ironstone, and porphyry in the basal part. Minor amounts of dark grey carbonaceous shale are interbedded with the sandstone. In the Sikanni Chief River section north of Pink Mountain the basal beds of alternating sandstone and shale, as exposed on Pink Mountain, are apparently missing. There a seam of coal 2 inches thick marks the base of the formation and is overlain by coarse sandstone containing scattered pebbles. On a tributary stream of Minaker River, 28 miles farther north, the base of the group is marked by a 3-inch conglomerate bed composed of pebbles of quartzite, chert, porphyry, and vitreous quartz, and is overlain by a 12-inch bed of coarse, sugary, quartz sand and dal. grey, coarse- to medium-grained, quartzitic sandstone, Only the
