This interactive map of part of the Colville River, Northern Alaska, shows the locations of plant fossil collections made by J.T. Parrish and R.A. Spicer in 1985 and 1989. Click on a number for more details on that site. The red outlined area links to another map showing positions of florules (plant fossil assemblages) collected by C.J. Smiley along both the Colville and Chandler Rivers.
This locality occurs in the Lower Killik Tongue of the Chandler Formation of Chapman et al. (1964), now the upper lower half of the Nanushuk Formation of Mull et al. (2003). All fossil samples were recovered from float. Here the dip is into the bluffs and the collection was effectively along strike. Fine lenticular cross-bedded sandstones contained log impressions, ginkgos, Cephalotaxopsis, Podozamites and entire-margined cycadophytes together with a variety of primitive-looking angiosperm leaves.
