Chukchi sea from top of jbg 65

The Chukchi Sea

From the top of Section 65 you can see the Chukchi Sea. The beach is about 75 feet below you here. The top of the cliff and the gully here are heavily slumped, so it is difficult to see exactly what the sediment layers look like.

The Chukchi sea is part of the Arctic Ocean. It lies northwest of the coast of Alaska.

From here you can:
Climb down to the entrance of the gully.
Climb down into the gully.
Cross the gully and look at deformed sediments lower down on other side.
Look at the sediments on the cliff face just below you.
Walk out onto the tundra.
Cross over to the top of Section 20.

Sources: The chief reference on the stratigraphy of the Gubik is (Brigham,1985). The best reference on the fossil molluscs from the Gubik is still (MacNeil, 1957). Recent papers on the age and climate history of these deposits include (Brigham-Grette and Carter, 1992; Kaufman and Brigham-Grette, 1993 Brigham-Grette and Hopkins, 1995).
