The western Grand Canyon is a natural laboratory for investigating processes of continental extension due to the great vertical exposure (> 1 km) and the relatively simple pre-extensional structure. We have undertaken a detailed field study of joint frequency in Parashant Canyon, a natural cross-section through the normal fault related Lone Mountain monocline, in order to better understand the role that joints play in accommodating extensional folding. The Lone Mountain monocline is made up of two half-monoclinal flexures: a hanging wall fold in which dips gradually increase toward the fault from a regional dip of 2° to a maximum dip …
