DOCUMENT
Full-Text
Six samples of botanic remains recovered from drill core samples collected in 1983 were submitted for identification. These remains most likely represent plants growing on the land surface in the Portland, Oregon, area prior to being covered by Missoula flood deposits around 15,000 years ago. The botanic samples were submitted for identification before possible radiocarbon dating.
