- Comments
- NjVm-VP, Komakuk: J-S. Vincent comments that at the collection site, two distinct sequences of organic-rich silty tundra pond deposits rested on glaciomarine sediments of the Flaxman Member of the Gubik Formation (Carter, et al. 1986). TO-651, on fecal pellets, dates the lowermost sequence, and GSC-4342 on willow wood (9900 +/- 200 BP, normalized) dates the uppermost one. These dates indicate that vegetation was well established and that tundra ponds were evolving through thermokarst actitity at the end of the Late Wisconsinan and during the earliest Holocene. Plants and insects recovered from the peat were identified by J.V. Matthews, Jr., and they indicate that conditions at the time of deposition of the tundra pond deposits were probably similar to those of the present.
