Coniferous woods from the Kogosukruk Tongue of the Prince Creek Formation (Campanian-Maastrichtian), central North Slope, Alaska (U.S.A.) have narrow growth rings, abundant false rings, and high ratios of late wood to early wood. These characteristics are the same across several taxa, and suggest that summers were cool and growing conditions variable. When compared with woods from the middle Cretaceous Nanushuk Group of the North Slope, the growth-ring characteristics of the Kogosukruk Tongue support conclusions that climate deteriorated substantially on the North Slope during the Late Cretaceous.
