Point Lobos Marinos Field Trip: Carmel, CA

Objectives: Geologic mapping by topographic inspection of geological units at Point Lobos State Reserve, Carmel, California. Using a topographic base map, we will locate our positions by inspecting the local topographic contours, pacing, and compass direction. At each station, we will record data on (1) lithology and (2) geologic structure. At some stations, we will also complete a sketch map or drawing of the geologic field relationships.

Outcomes: By the end of this day, you will have participated in the romantic side of geology, Field Geology. There is no better place to do your work than the outdoors (this is why most geologist pick exotic islands or tropical beaches to do their field geology).

Products: You will produce a geologic map with marked field stations, lithology contacts, geologic structures. You will depict the different rock units in the area mapped with colors (Red for Santa Lucia Granodiorite; Blue for the Carmelo Formation; Brown for marine terrace deposits). Your map will have a legend form oldest to youngest units (Santa Lucia Granodiorite = 80 to 100 Ma; Carmelo Formation = 60 Ma; Marine Terrace Deposits = 1.6 Ma to Recent). You will also take legible and careful notes in a field notebook. This notebook will include descriptions of each geologic unit and geologic structure in the field area. Finally, your notebook will also include the sketches or drawings of the lithology contacts and structures.

Final Report Your final product will be a geologic map and accompanying geologic history written report (2-3 pages). You will turn in a (1) complete geologic map with legend, (2) written geologic history (2-3 pages), (3) notebook with field stations and sketches.
