Wasatch Mountains, Utah Thrust Faults and Folds

Sevier-Laramide Project:  Wasatch Mountains, Utah See exposures of Sevier (Cretaceous) thrust faults and folds at Payson Canyon, Springville, Mt. Timpanogos, Salt Lake City, Strawberry River, Park City, Ogden Canyon, and Willard Payson Canyon Thrust Watch a drone flyover of the Payson Canyon thrust:   Watch on YouTube   A thrust fault is mapped in Payson Canyon on the 1991 Nephi 30x60 geologic map, placing Cambrian through Mississippian strata against Pennsylvanian at this location. The map, however, shows the younger Pennsylvanian strata as being displaced over the older strata, which would be incorrect.  Either way, this is the only thrust fault exposed in the Mt. Nebo block, and is therefore of geologic interest.  Older maps showed thrusts on the southern side of Nebo, but more recent geologic maps have reinterpreted them as landslides and different strata.  The Charleston-Nebo thrust is buried on the east side of Nebo by Neogene volcanics. ...

Pavant Thrust, Central Utah

 Sevier-Laramide Project: The Pavant Thrust near Fillmore, Utah See one of Utah's best-exposed thrust faults in the scenic and accessible Pavant Mountains! Notes Travel :  Fillmore has hotels and accommodations, and is located conveniently along Interstate 15. Access :  The canyon and mountain roads provide good access into the mountains.  They're rocky and steep in places, requiring tires and clearance appropriate for the terrain.  I'd only take a car into the lower parts of either canyon. Camping :  Chalk Creek and Kanosh Canyons have good campgrounds and primitive campsites.

Canyon Range thrust, Utah

Canyon Range Thrust, West-Central Utah Sevier-Laramide Project Looking north in East Fork of Eightmile Creek in the Canyon Range. The Canyon Range is the place the Sevier orogeny is named for because the thrust faults are parallel to the Sevier River, and the river sweeps around the north end of the range to empty into the Sevier desert.  It's a natural!  Of all the places where I've visited the Sevier faults and folds, this may be my favorite because of its unique scenery, beautiful quartzite bedrock, remoteness, and geologic significance. The range is made of Proterozoic metasedimentary rocks (quartzite, metasiltstone, and slate) overlain by Cambrian, Ordovician, and Silurian sedimentary rocks.  The rocks here are beautiful!  I went home with hundreds of pounds of quartzite with cross-bedding, coarse clasts, and colorful bands.   Access on the south end is by primitive 2-track roads that are rocky, rough, narrow, and little used, so I advise a good 4WD (...
