Basic information
Sample name: Fantasia
Sample aka: Carter Mountain; UW V-78001
Reference: J. G. Eaton. 1982. Paleontology and correlation of Eocene volcanic rocks in the Carter Mountain area, Park County, southeastern Absaroka Range, Wyoming. University of Wyoming Contributions to Geology 21(2):153-194 [ER 4142]
Geography
Country: United States
State: Wyoming
County: Park
Coordinate: 44.29° N, -109.25° W
Latlng basis: stated in text
Formation: Wiggins
Time interval: Early Eocene
Zone: Bridgerian
Ma: 48.41
Age basis: Ar-Ar
Geography comments: shown in Fig. 18 as within the Blue Point marker just under the base of the Wiggins Formation near the north end of Carter Mountain
"in sec. 21, T. 50 N., R. 103 W." (see Fig. 17)
the Blue Point marker is not assigned to a formation because it underlies both the Wiggins and the Tepee Trail and overlies both the Wapiti and the Aycross (Fig. 5)
thought to be equivalent to Bridger B or C
there is a "K:Ar date of 47.9 my ± 0.5 my" on the Blue Point marker (p. 190), which is just younger than the top of the Early Eocene
the marker has since been dated at 48.41 ± 0.17, apparently using Ar/Ar dating (Tsukui et al. 2012)
