Geologist examines steeply dipping, overturned contact between Jurassic Kingak Shale (left) and Lower Cretaceous Kemik Sandstone, which is overlain at right by Lower Cretaceous pebble shale unit. This outcrop, along Hue Creek at the northern front of the Shublik Mountains, northeast Brooks Range, preserves the same stratigraphic relationship that extends across much of the North Slope and Chukchi Shelf. Light colored rocks at upper left are Proterozoic Katakturuk Dolomite, thrust northward over the Kingak Shale.
