POLLEN ANALYSIS AT THE DJ RANCH AND BOWLING DUNE SITES, PORT ROCK BASIN, OREGON

Summary

The Bowling Dune and DJ Ranch sites are both located near ancient lakes and

channel systems associated with the Silver Lake overflow system. During early

and mid-Holocene water filled these overflow systems and ran out of Silver Lake

valley sub-basin into the Fort Rock Valley sub-basin. Pollen analysis was

undertaken at the Bowling Dune and DJ Ranch sites to identify whether or not

wetlands were present near both sites at the time of occupation. In addition,

dark soil lenses without associated cultural debris were noted at both sites.

Pollen analysis was undertaken on samples from these lenses to determine whether

they formed as a result of dense plant growth on moist soils or exhibit charcoal

from range fires.
