Summary

Description

This is Split Mountain in Dinosaur National Monument, Utah, through which the Green River has erosionally carved a prominent canyon (off frame, to the left). The rocks at upper left are eolian sandstones of the Weber Sandstone, a thick, Pennsylvanian- to Permian-aged unit representing ancient sand dune deposits. The Weber is the principal cliff-forming unit in the park.

At center are multicolored sedimentary rocks of the Park City Formation, a Permian-aged, marine, heterolithic, slope-forming unit. Here, it is principally reddish and yellowish shales. At lower right is a hematite-rich, fine-grained siliciclastics unit called the Moenkopi Formation (Triassic).

Stratigraphy: Park City Formation, Permian

Locality: southern flanks of Split Mountain, Dinosaur National Monument, northern Uintah County, northeastern Utah, USA (40° 26' 39.76" North latitude, 109° 15' 01.22" West longitude)
