Western North Slope Foothills
The Kukpowruk River cuts through folded Cretaceous rocks in the central North Slope. These rocks were assessed by the USGS in 2017 and lie above the rocks assessed in the USGS 2021 Western North Slope assessment.

Kokolik River Oil Sand
Oil-saturated sandstone in the Nanushuk Formation in westernmost National Petroleum Reserve in Alaska (NPR-A). Oil in these rocks likely was generated beneath Western North Slope and migrated northeastward into NPR-A.
