Today we ventured out Cottonwood Road into the Grand Staircase to an area that we've visited before and, no doubt, will visit again: The Cockscomb. This is an area where the sedimentary layers have been thrust upward along another monoclinal fold. This fold is known as the East Kaibab Monocline and stretches from near Flagstaff, Arizona to the Table Cliffs a short distance from Bryce, a total length of some 240 km (150 miles). I need to verify but believe the rock to be Carmel Formation and Entrada Sandstone, both from the mid-Jurassic. There's a whole series of these formations jutting skyward along the road along with some other interesting things that will require a visit earlier in the day sometime soon.
