STUDENT’S MANUAL for 2000 NORTH CAROLINA UNIVERSITIES SUMMER FIELD COURSE in GEOLOGY by P. Geoffrey Feiss Richard Mauger Kevin G. Stewart 1 Acknowledgments This manual has evolved over a decade with the help and assistance of many faculty, TAs, and staff — some forgotten, some not. Among those who deserve thanks are John Bartley, Mary Crump, Cathy Cash, Allen Glazner, Stephen Harper, Richard Spruill, Charles Daniel, Jim Reynolds, Terri Woods, Rick Wooten, and Patsy Webb. © copyright USA 2000 All rights reserved 2 Schedule for 2000 Field Course Date Day Activity 12-May Fri leave North Carolina; Trip West; camp at Cedars of Lebanon State Park, TN 13-May Sat Trip West; camp at Red Rock Canyon State Park, Hinton, OK 14-May Sun Trip West; arrive Abiquiu, NM camp site 15-May Mon Abiquiu, NM; Intoductory Geologic Mapping Project 16-May Tue Abiquiu, NM; Intoductory Geologic Mapping Project 17-May Wed Abiquiu, NM; Intoductory Geologic Mapping Project 18-May Thu Abiquiu, NM; Intoductory Geologic Mapping Project 19-May Fri Taos, NM mapping and landslide project 20-May Sat Taos, NM mapping and landslide project 21-May Sun Taos, NM mapping and landslide project 22-May Mon Taos, NM mapping and landslide project 23-May Tue Taos, NM mapping and landslide project 24-May Wed Taos, NM mapping and landslide project 25-May Thu Taos, NM mapping and landslide project 26-May Fri Field trip, Great Sand Dunes , CO and Raton Basin, NM 27-May Sat Field trip, Great Sand Dunes , CO and Raton Basin, NM 28-May Sun Field trip, Great Sand Dunes , CO and Raton Basin, NM 29-May Mon Cuba, NM, Mapping and hydrology projects 30-May Tue Cuba, NM, Mapping and hydrology projects 31-May Wed Cuba, NM, Mapping and hydrology projects 1-Jun Thu Cuba, NM, Mapping and hydrology projects 2-Jun Fri Cuba, NM, Mapping and hydrology projects 3-Jun Sat Cuba, NM, Mapping and hydrology projects 4-Jun Sun Cuba, NM, Mapping and hydrology projects 5-Jun Mon Cuba, NM, Mapping and hydrology projects 6-Jun Tue Cuba, NM, Mapping and hydrology projects 7-Jun Wed Field Trip, Mesa Verde, CO and Creede, CO 8-Jun Thu Field Trip, Mesa Verde, CO and Creede, CO 9-Jun Fri Field Trip, Mesa Verde, CO and Creede, CO 10-Jun Sat Gunnison Projects, East Elk Creek campground 11-Jun Sun Gunnison Projects, East Elk Creek campground 13-Jun Mon Gunnison Projects, East Elk Creek campground 14-Jun Tue Gunnison Projects, East Elk Creek campground 15-Jun Wed Gunnison Projects, East Elk Creek campground 16-Jun Thu Gunnison Projects, WSC dorms 17-Jun Fri Gunnison Projects, WSC dorms 18-Jun Sat Gunnison Projects, WSC dorms 19-Jun Sun Gunnison Projects, WSC dorms 20-Jun Mon Gunnison Projects, WSC dorms 21-Jun Tue Gunnison Projects, WSC dorms 22-Jun Wed Gunnison Projects, WSC dorms, pack for trip east 23-Jun Thu Trip East, camp at Wilson Lake State Park, Sylvan Grove, KS 24-Jun Fri Trip East, camp at Cedars of Lebanon State Park, TN 25-Jun Sat Trip East; arrive Raleigh/Chapel Hill, NC late afternoon MAILING ADDRESSES Before June 1 UNC System Geology Field Course c/o Circle A Ranch, Box 2142, Cuba, NM 87013 After June 1 UNC System Geology Field Course c/o Aspinall-Wilson Center Western State College, Gunnison, CO 81230 3 CHAPTER 1 - GENERAL INFORMATION ACADEMIC MATTERS Grading Policy - Independent Work If a student is found to have in his/her possession a copy or copies of map(s) or reports(s) from previous years, the student will be immediately dismissed from the field course.1 All material submitted by you for a grade will represent independent work. This is not as simple as it sounds. In all field exercises you will be working with a field partner and, in addition, we wish to encourage the free exchange of ideas in the field and in “bull sessions” - whenever the spirit moves you. Operationally, the concept of independent work boils down to this: •All data on your maps and in field notes was observed by you. •All work submitted for grading was done by you. An example may suffice. Suppose that in a discussion with another group in the field, you and your partner become aware of an important structure that you had missed in your mapping. On that basis alone, it would not be appropriate to enter that structure on your map or submit your map with that structure shown. You would be advised to enter the idea in your field notebook properly acknowledged as to the source of the idea. How- ever, there is no reason why you and your partner could not, on the basis of that discussion, return to the area in question, see the structure, and then enter the appropriate data on your map (in fact, you may return to the area in question and decide that the other group is completely wrong!). What you call your work must be your own work. We encourage the sharing of ideas and observations (not data) with one another. This is integral to the learning experi- ence. Here’s an example: you encounter a couple of students measuring a strike and dip on an outcrop. You, too, plan to measure the strike and dip of this formation. As you approach, you hear one partner say to the other, “Strike N38W, Dip 51 SE”. What do you do? Hint: you do not enter that in your field notes and walk on. You inspect the outcrop yourself and make your own measurements. After all, they might have measured a foliation, not bed- ding, or been wearing a highly magnetic belt buckle and got the dip in the wrong direction. Problems may arise if you are not careful and circumspect with your maps and field notes during the evenings and other times. Should you leave your map in open view and unattended, you are nearly as guilty as someone who copies from that map — in a court of law you would be held accountable for entrapment. Keep your maps and notes secure and out-of-harm’s way. Do not tempt your colleagues. Unfortunately, it is not unusual for us to hear, six months later, that “so-and-so” copied every map — “everybody knew this”. The problem is that “everybody” but the faculty and TAs know. If you know of such cheating, it is your responsibility to stop it — by confronting the student or reporting it. Why should you expect a TA or faculty member to confront an unknown student not known to have committed grievous acts of unreported dishonesty. 1 For UNC-CH students, this is also an Honor Code violation. 4 Due Dates Course grades are determined on the basis of assigned field course projects. Due dates (subject to revision at the instructor’s discretion) for these projects will be made abundantly clear at the beginning of each exercise. The specific requirements for each of these projects will be spelled out at the same time. Generally speaking, an inked and col- ored geologic map, a stratigraphic column, and possibly one or more structure cross-sec- tions will be required. In some instances a narrative or a description of the lithologic units may also be necessary. The grade reported is based on submitted, graded work combined with the faculty’s subjective impressions of your performance in the field. This latter is based on observation and discussions with each of you in the field by the instructors. The faculty are not grading you on what you know or do not know in the field. They are aware of your motivation, your willingness to contribute to the mapping project, your interest and enthusiasm, your developing field skills and many other factors. The instructors are there to supply guid- ance, answer questions, and observe your progress. It is unlikely that circumstances exist in which it would be advantageous to avoid the instructors while in the field (a course some individuals have chosen in the past). If the instructors never see you, they can neither help you nor give you the benefit of the doubt in grading. This Course Manual This manual should be your Bible/Koran/Torah. It contains instructions, a guide to field methods, guidelines for preparing maps and cross-sections, and lots of useful geologi- cal information. We appreciate constructive comments for future editions. Your instructors may give reading assignments and hold you responsible, at any time, for short quizzes on the manual contents. Be forewarned. We assume that you will have read the manual thoroughly prior to leaving on the trip west from North Carolina. Policy on Making Up Missed Field Work If, because of illness or injury, a student misses a portion of the field work, arrange- ments will have to be made with the faculty in charge of that project as to how this work is to be made-up so that you can submit a complete map. If a student misses a large portion of field time, it is left to the judgment of the faculty and the field camp director to suggest that the student withdraw from all or a portion of the course and repeat the work in a subsequent field season. If injury occurs as a result of carelessness or negligence on the part of the student, especially if that injury occurs during the student’s free time, the faculty will be notably less sympathetic about making special arrangements than if the student is injured in the normal course of field work. RULES AND REGULATIONS Over the years, we have developed a set of rules and regulations to govern various aspects of behavior at field camp.
