Geography
Country:United States State/province:Utah
Coordinates: 37.6° North, 112.1° West (view map)
Paleocoordinates:45.7° North, 83.3° West
Basis of coordinate:estimated from map
Altitude:2099 meters
Geographic resolution:small collection
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Stage:Campanian 10 m.y. bin:Cretaceous 7
Key time interval:Middle Campanian
Age range of interval:83.60000 - 72.10000 m.y. ago
Stratigraphy
Formation:Wahweap
Stratigraphic resolution:bed
Stratigraphy comments: "approximately Aquilan"

Jinnah et al. 2009: The ash horizon, located ~40 m above the base of the Wahweap Formation, yields an age of 80.1 +/- 0.3 Ma. The new radiometric data improve upon previous biostratigraphic age estimates for the Wahweap Formation and indicate that the formation was deposited between approximately 81 and 76 Ma. The youngest population of detrital zircons from the base of the Wahweap Formation clusters around 83–82 Ma, while the youngest population in the capping sandstone near the top of the formation is between 77–81 Ma, consistent with the 40Ar-39Ar age.
