Step Mountain is aptly named for several resistant Tertiary-age andesite dikes that display exceptional horizontal columnar joints.

Cretaceous Mancos Shale, Uinta Basin, Utah

A research team from the Utah Geological Survey and the University of Utah presented the results of their on-going work in the Uinta Basin to members of the petroleum industry recently. Meeting in Denver on June 28, the UGS and university geologists discussed their research on the oil and gas potential of the Cretaceous Mancos Shale, which lies several thousand feet below the surface in most of the Basin. Although oil and gas from shale have made energy headlines in many states, production from the Mancos will be a challenge, due in part to its thickness compared to other U.S. shale plays. About 20 geologists and engineers representing 10 companies with interests in the Uinta Basin attended the meeting. The research is being funded by the Research Partnership to Secure Energy for America, through a contract from the U.S. Department of Energy.

Framed by blooming gray rabbitbrush (Chrysothamnus nauseosus) above the east shore of Deer Creek Reservoir, Mt. Timpanogos is formed of Pennsylvanian-age, shallow- marine limestone and sandstone of the Oquirrh Formation. The small patch of snow is in Cascade Cirque, one of several glacier-carved basins on the east side of the 11,749-foot-tall mountain.

The Waterpocket Fold affords a wonderful view of the geology of Grand Gulch. The Entrada Sandstone (reddish-orange rock on the right) and Navajo Sandstone (pale-orange rock on the left and middle distance) were formed in a desert  environment beginning about 185 million years ago in the Jurassic Period.

Cookie Jar Butte, named for the gigantic, cylindrical weathering pits that dot its peninsula, towers above Padre Bay on Lake Powell.

Dollar Lake, High Uintas Wilderness, Duchesne County, Utah
Photographer: Mike Hylland

To the south of Dollar Lake in the Uinta Mountains, cliffs of Precambrian-age sedimentary strata rise abruptly at the head of the Henrys Fork basin. The leftmost peak lit by the morning sun is Utah’s highest mountain, Kings Peak (13,528 feet), which was named for Clarence King, first director of the U.S. Geological Survey.

Locally known as Devils Postpile, this andesite intrusion in the southern Cedar Mountains displays well developed columnar cooling joints.

On April 18, 2013, four geologists from the Hazards Program of the Utah Geological  Survey flew along the Wasatch Front in a Utah Air National Guard Blackhawk helicopter. The flight was part of the Great Utah ShakeOut 2013 earthquake drill, as well as an opportunity to take high-resolution photos  of the fault scarps along the Front from the air. The four geologists were Adam Hiscock, Gregg Buekelman, Mike Hylland, and Adam McKean. It was a freezing cold day in April! Over 1200 photos were taken from the air.
