Field Trip Your are required to attend one of the field trips. Dates: May 11-13 or May 18-20 Each student must attend one (and only one) of the two field trips. The field trip is to Grand Canyon and surrounding areas in Arizona. It will familiarize you with a broad range of concepts covered in lecture, lab and on the problem sets. The first day will include examination of Sunset Crater, AZ, a recently active volcano, and walking through the Permian Coconino, Toroweap and Kaibab Formations that rim Grand Canyon. The second day will include examination of igneous and metamorphic rocks and an ancient erosion surface called the Great Unconformity west of Seligman, AZ, followed by study of a volcanic formation called the Peach Springs Tuff near Kingman, AZ, which records a gigantic, explosive volcanic eruption that occurred 18 million years ago. More details are provided below. |

The horizontal layering are strata deposited during the Paleozoic Era, between 543 and 250 million years ago. The dark cliffs in the deepest part of the canyon in the lower left part of the photo are the eroded remains of a mountain belt that formed 1.7 billion years ago. | ||||||||
