- Comments
- Grotte Valerie, JhTm-VP: Wood samples were colleted from the floor of the cave (Grotte Valerie) in limestone. The cave temperature is relatively constant, with seasonal variations a few degrees above or below freezing. The cave also contains numerous skeletons of Dall's sheep (Ovis dalli). General Comments on the series (G.O. Lee): GSC-1727 is considerably younger than GSC-1634, which was taken from the same general vicinity in the cave. These dates, in conjunction with other C-14 dates on the skull of a Dall's sheep and uranium series dates on stalactites, will help to trace the historic development of the caves as well as to reconstruct the development of plant communities in this unglaciated terrain.
