A field guide is always a handy, but rare, little document, especially for a secondary educator. Therefore, the purpose of this project was to research, develop, write and present this document, for the Landels-Hill Big Creek Reserve. The University of California Natural Reserve System oversees thirty-six multi-acre, natural reserves. One part of the overall mission of these reserves is an educational outreach program in which curriculum is made available to the school systems. The curriculum is to be used to educate the students about each specific reserve area, to engage students in learning about their environment and to create an awareness of the need for conservation of wild areas. The final products from this research are a secondary-level geology guidebook, for students, with suggested classroom and in-field lessons, specifically written for the Landels-Hill Big Creek Reserve, Big Sur, California, along with a revised and updated geologic map of the Reserve and a teaching rock collection, for use at the Reserve. / text
