The Hand Hills erosional remnant (covering an area of 30 km x 15 km) in south central Alberta exposes a sequence of upper Maastrichtian to middle Paleocene continental sediments with a thin cap of plateau-forming Miocene to Pleistocene gravels. Roadcut and auxiliary outcrop sections on the south and north sides of the hills provide a composite total section from the Whitemud Formation at the base to the Paskapoo Formation at the top. Magnetostratigraphy, coupled with palynology, shows the presence of magnetozones 30, 29r and 29 in the south (Whitemud, Battle and Scollard formations), including the Cretaceous-Tertiary boundary coal seam, but not the ＇＇boundary clay＇＇. A 23 m thick, brown-weathering sandstone, previously taken to be the basal Paskapoo sandstone, is interpreted to be part of the Scollard Formation. The northern section exposes the Scollard, Paskapoo and Hand Hills formations and magnetozones 30, 29r, 29, 28r, 27 and 26r. The K-T boundary coal seam is missing at a minor disconformity. Although no major sandstones occur in the section, the palynology and magnetostratigraphy indicate a major ＇＇sub-Paskapoo＇＇ disconformity beneath a 3 m sandstone, representing magnetozones 27r, 28 and part of 28r. Two Tiffanian mammal sites occur near the top of the section. The lower one, at least, occurs near the base of 26r.
