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.

A little more than a year ago, in the corner of a Salt Lake City tattoo parlor spattered with sci-fi ephemera and fantasy art, I watched as artist Jon McAffee inked an Allosaurus onto my arm. The bloody art was a celebration of a dream realized and a promise to myself.
The giant, sauropod-rending theropod Allosaurus is the state fossil of Utah, and a symbol of why I transplanted myself to the state. I moved west for the dinosaurs. But the tattoo represents more than that. I’m not content only writing about dinosaurs. I need to seek them out; to dig them from their resting places and contribute something to our understanding of prehistory. Allosaurus – the most common terror of 150 million year old Utah – was at the top of the list of the dinosaurs I wanted to meet among the badlands.

Delicate Arch is formed of Jurassic-age sandstone—the Slick Rock Member of the Entrada Sandstone (base and pedestals) and Moab Member of the Curtis Formation (bridge). With a horizontal span of 32 feet and a vertical span of 46 feet, Delicate Arch is small compared to many other natural arches, but its free-standing nature makes it unique in the world and emblematic of Utah’s spectacular red-rock geology.
