Mirror lake, Uinta Mountains, Duchesne County, Utah
Photographer: Ken Krahulec
Mirror Lake nestles among 11,000-foot peaks of the western Uinta Mountains. The rocks of the Uintas, consisting largely of sandstone and shale of the Precambrian-age Uinta Mountain Group, contain microscopic bacteria nearly 800 million years old that likely represent Utah’s oldest fossils.

The Kanarraville quadrangle includes the southern part of Cedar Valley and parts of the adjacent Kolob Terrace, Harmony Mountains, and North Hills. It straddles a particularly instructive area of structural overlap between the Sevier fold thrust belt-represented by the overturned, east limb of the Kanarra anticline exposed at the west edge of the Kolob Terrace-and the Basin and Range physiographic province, whose east margin corresponds to the Hurricane fault zone at the base of the plateau. Regional ash-flow tuffs erupted from calderas in western Utah and eastern Nevada are present in the Harmony Mountains and North Hills; in the Harmony Mountains, these tuffs are involved in a large gravity slide shed off the nearby Stoddard Mountain laccolith, which erupted to produce an ash-flow tuff now partly buried by the gravity slide.
This CD contains the geologic map at 1:24,000 and a 31-page booklet describing the geology of the Kanarraville 7.5-minute quadrangle. All of the files are in PDF format. The latest version of Adobe Reader is required to view the PDF files.

Baked by the summer sun, clay on the floor of an ephemeral pond in Utah’s west desert produces an expanse of mud cracks. Such playas, or pans, are common throughout the Great Basin; many, like the Bonneville Salt Flats, are floored by saline minerals.

A 656-page book chronicling the paleontological discoveries and success evidenced so far at Utah’s Grand Staircase-Escalante National Monument has been published, even as new discoveries continue to unfold on a near daily basis.
“I am here to emphasize that we are just getting started at the Grand Staircase,” said Alan Titus, the monument’s paleontologist. “We have a great big sandbox to play in.”
