THE LEWIS AND CLARK TRAIL: EXAMINATION OF PIT FEATURES FROM FORT CLATSOP, OREGON FOR POLLEN, PHYTOLITHS, PARASITES, STARCH GRANULES, AND MACROFLORAL REMAINS; AND POLLEN, PHYTOLITH, AND MACROFLORAL ANALYSIS OF SEDIMENT FROM FIRE FEATURES AT LOWER PORTAGE CAMP, MONTANA

Sediment from a suspected privy pit and a post hole at Fort Clatsop, Oregon, was examined for pollen, starch, parasites, phytoliths, and macrofloral remains to obtain information that might assist in identifying the function of these pits. The presence of parasite eggs and/or recovery of probable food remains are used to determine a privy function. Three fire features and an area of possible cooking pot spill at the Lewis and Clark Lower Portage Camp in Montana also were examined for pollen, phytoliths, and macrofloral remains. These analyses will provide a record of vegetation and possibly indicate food resources utilized by the expedition at this camp.
