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 is an exposure of the Lower Killik Tongue of the Chandler Formation of Chapman et al. (1964), now the upper part of the lower half of the Nanushuk Formation of Mull et al. (2003), consisting of a sandstone and shale succession. The sandstones are crossbedded with pronounced pebble stringers, ripple marks, abundant water-worn wood fragments, and are often rooted. Unidentified platanoid leaves were found as float at the base of the cliffs. No other plant fossils were seen.
