Also known as The Pinnacles
Where: Fremont County, Wyoming (42.4° N, 108.9° W: paleocoordinates 47.2° N, 92.3° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Lostcabinian zone, Main Body Member (Wasatch Formation), Wasatchian (55.8 - 50.3 Ma)
• Clyde et al. 2001 took paleomagnetic samples through this part of the section but they were too poorly preserved to analyze
• member-level stratigraphic resolution
Environment/lithology: fluvial-lacustrine; brown shale
Size classes: macrofossils, mesofossils
