Devils Garden, Grand Staircase–Escalante National Monument, Garfield County, Utah
Photographer: Ken Krahulec

Metate Arch is sculpted by weathering and differential erosion of two sandstone layers along the contact of the Gunsight Butte and overlying Cannonville Members of the Jurassic-age Entrada Sandstone. The arch is about 17 miles southeast of Escalante, just east of the Straight Cliffs.

What in the world is a gooseneck? When it comes to describing a landform, fowl play (pun intended) may seem apparent. Even when you are standing in front of one, the answer is not obvious. Not until you get a look from above does this name start to make sense.

The White River carved this amphitheater in the flat-lying and remarkably parallel rock layers that were deposited in a Tertiary-age lake on the south flank of the Uinta Mountains.

Henry Mountains, Garfield County, Utah
Photographer: Ken Krahulec

The “dome” character of a laccolith, where the sedimentary rock layers are tilted upward on the mountain flanks, is evident at Mount Ellsworth in the Henry Mountains, Garfield County.

The La Sal Mountains, near Moab in southeastern Utah, are laccoliths formed when upwelling magma intruded into and bulged the overlying sedimentary rock layers upward. The magma did not reach the surface, but subsequent erosion of the softer sedimentary rocks exposed the peak-forming igneous rocks that rise above the surrounding landscape.
