Utah: A geologist’s wonderland

Chetan Patel (USA) Often referred to as the Red Rock Country, the state of Utah boasts some of the most breathtaking landscapes formed from years of erosional artistry. Dominating this impressive landscape is the Colorado Plateau that spans the four states of Colorado, New Mexico, Arizona and Utah. Adjacent to the Colorado Plateau, separated by the Wasatch Fault Zone, is the Basin and Range Province, another expanse of geological wonder formed during the Laramide Orogeny. These spectacular landscapes, dominated by the eponymous red rock, offers geologists a great opportunity to study both modern and ancient processes in great detail. With favourable weather and easily accessible outcrops, Utah serves up an exciting geological journey. Fig. 1. Map showing extent of the Colorado Plateau. Within Utah, resides what is commonly referred to as the mecca of sequence stratigraphy, the Book Cliffs. These offer a wonderland of stratigraphic sequences to the travelling geologist. In fact, hosting a wide variety of easily-accessible outcrops, Utah has become a premier location for the study of sequence stratigraphy, specifically in the oil and gas industry. The well-exposed outcrops offer a detailed look into facies relationships providing the perfect outcrop analogues to subsurface exploration. The name “Book Cliffs” was coined by the early settlers of the region to which the alternating layers of shale and sandstone resembled the pages of a book on its side. Fig. 2.
