CONNECTING PARK VISITORS TO PARK GEOLOGY IN YOSEMITE NATIONAL PARK VIA GEOLOGY-BASED INTERPRETATION
In order to increase the geologic content of interpretive programming at Yosemite National Park, I am designing a geologically-based, illustrated training manual for the park's interpretive staff. Increased geologic background will encourage interpretive rangers to make more connections between the physical landscape and other important aspects of the park such as landforms, flora, fauna, people, rock climbing, and climate change. The goal is to disseminate local and regional geology via a thematically organized, illustrated training manual. Presenting geology in thematic ways will help rangers with diverse backgrounds connect visitors to the fantastic geologic features and processes they experience in Yosemite National Park. The training manual will emphasize three main processes: 1) subduction of the Farallon plate under the North American plate and granite petrogenesis; 2) uplift of the Sierra Nevada and exhumation of the granite; 3) Quaternary glacial cycles and the resulting geomorphology. These processes will be presented through interpretive strategies rangers can utilize when giving presentations on a variety of aspects of natural and cultural history.
