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. Metate Arch, Devils Garden Outstanding Natural Area, Garfield County, Utah Photographer: Ken Krahulec; © 2014

Geologic Map of the Haycock Mountain Quadrangle, Garfield County, Utah

By: Robert F. Biek, John J. Anderson, Edward G. Sable, and Peter D. Rowley

The Haycock Mountain quadrangle lies in the central part of the Markagunt Plateau in southwest Utah and includes the eastern part of Panguitch Lake, a popular area of summer and winter recreational use. Despite the plateau’s relatively simple structure of a gently east-tilted fault block, the quadrangle contains scenic and instructive exposures of south-west Utah’s youngest basaltic lava flows, classic examples of inverted valleys capped by older lava flows, and the southern margin of the Markagunt Megabreccia, including newly identified, exceptionally instructive exposures of its basil slip surface. The Megabreccia is the debris of Utah’s largest catastrophic landslide deposit, which covers 1300 square miles (3400 km²) of the northern and central Markagunt Plateau.

Colorful volcanic sandstone and mudstone of the Brian Head Formation record initiation of volcanic activity in southwest Utah about 36 million years ago. Here, Eocene-age Brian Head deposits form rugged badlands at the south end of the Sevier Plateau.
