ERTH 137 and 138 - Introductory Field Geology and Geologic Field Camp

ERTH 137: June 19 - July 11, 2023

ERTH 137 - Introductory Field Geology is a 4.5 unit course offered in second half of summer session 1.  The first two weeks in Santa Barbara, and the last few days in the White-Inyo Mountains, near Bishop.  This course introduces the student to the tools and techniques for geologic mapping in the field.  No previous field mapping experience is required.  Techniques covered include:  Introductory Field Mapping with Brunton Compass and Tape, Stratigraphic Mapping Sections, Interpretation of Topographic Maps, Geologic Maps, Geologic Cross Sections.  The course is offered both in the lab and in the field.  Homework assignments are required.

ERTH 138: July 15 - August 2, 2023

ERTH 138 - Geologic Field Camp is a 4.5 unit course with the first two weeks in the field and the last few days in Santa Barbara, writing up your final projects.  This course, during summer session 2, requires a previous mapping course (ERTH 137 is acceptable) or consent of the instructor.  Geologic Mapping is done at a field camp near Mt. Abel at an elevation of 6200 feet, in the Cuyama Badlands, and the Ridge Basin near Gorman.  It is an intense field-mapping course using various geologic surveying tools and techniques learned in ERTH 137.

We recommend that students have a lecture and lab course such as Dynamic Earth, although extensive background (Mineralogy, Petrology, etc.) is not required. These courses are recommended for any geology major who wants to get a head start in advanced field courses offered at major colleges and universities.  In fact, some universities allow this course to transfer for credit toward introductory field geology mapping courses.  Both of these courses are transferable as electives for the geology program.
These courses move fast and a lot of work is required in both classes.  It is going to be HOT with numerous bugs and flies, a lot of hiking and climbing, and you need to be focused!  To take these courses you need to be physically fit, mentally alert, able to work in teams, and emotionally stable!
ERTH 133 - Geology of Colorado Plateau is offered each summer while ERTH 137 and ERTH 138 are only offered every other summer.
