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.

Weighing type precipitation gage and new radar-based sensor
The Wolverine Glacier weather station was installed in 1968, and at 3250 ft is the highest elevation long-term weather record on the Kenai Peninsula. On October 19, 2020, USGS scientists upgraded the power system to a Lithium battery bank and installed a radar-based precipitation sensor (Lufft WS-100) to compare with the weighing based precipitation gage.

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.
