- Comments
- Dublin Gulch: All of the mid-Wisconsinan fossils recovered from this locality have been found by gold miners during their placer mining operations. As Harington (1996) notes, fossils have rarely been seen in situ by Quaternary scientists, and their original stratigraphic positions have been inferred, rather than documented. This may one reason why all of the identified taxa are large mammals. Presumbably it would be worthwhile to water-screen some of the colluvial sediment that is thought to represent the source at least some of the bones. Of course, it is possible that the existing collections were actully derived from more than one sedimentary layer, and the date on a single horse bone may not represent the chronological placement of the other taxa. For example, "there is no radiocarbon evidence that [the living species Alces alces] lived in Alaska and the Yukon before the Holocene" (Harington, 1996: 371). It will be important to date one of the Dublin Gulch moose bones.
