Kokolik and Kukpowruk Rivers

Introduction Northern Alaska Map     Kokolik River Kukpowruk River

 

The Kokolik and Kukpowruk Rivers transect the Albian to early Cenomanian Kukpowruk and Corwin Formations, non-marine sediments of which contain a rich record of forests before and immediately after the first arrival of flowering plants in the arctic.

The Kukpowruk River was first sampled by Smiley in the 1960s. In 1996 Herman and Spicer revisited Smiley's sections and made new collections along the length of the river.

In 1998 R.A. Spicer and A.J. Spicer floated and sampled the Kokolik before transerring to the lower reaches of the Kukpowruk River.
