Palynology
As noted in the proposal,
projects of this nature often lead to additional research. Although palynology
was not part of the original proposal, Dr. Orson was able to obtain two
students from Yale to conduct a preliminary palynological investigation
into the top 80 cm of peat. The results of that investigation are shown
in Figs 10 - 12. Figure 10 is a view of the percent pollen recovered from
a core in the unrestricted site and Fig. 11 is the material recovered
from the peat overlying the trolley fill. Fig 12 is a composit view of
the comparisons between all arboreal and non-arboreal pollen. The decline
in arboreal pollen on Fig. 12 coincides with the increase in ragweed on
Fig. 10 (Ambrosia sp.), suggesting that the colonial period at this site
occurred at about 40 cm, a depth that corresponds with the settlement
period noted at other sites in Connecticut (Orson et al 1998).
