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.

Storm clouds gather over Mount Belknap (12,137 feet) in the Tushar Mountains, Utah’s third-highest range. The smooth, rounded slopes of this summit ridge are composed of easily eroded volcanic ash and lava flows. The mountains are part of the eruptive center of the Marysvale volcanic field, an area of intense volcanic activity between 32 and 22 million years ago.

Alluvial and wind-blown sediment partly conceals the Jurassic-age Entrada Sandstone in the Last Chance Desert, which occupies the axis of the Last Chance anticline. The narrow, jagged, black ridge at the center of the photo is a basaltic dike of probable late Tertiary age (3 to 5 million years old) that intrudes the Entrada Sandstone.
