Speaker: Dr. Eleanora Robbins
The geology of the Santa Margarita watershed is fascinating--and in some respects it resembles many characteristics of the East African Rift Valley. The cities of Temecula and Murrieta lie in a tectonically active rift. Volcanic rocks and cryptic structures show that high heat flow has been evident over eons of time. Overprinted on the geological processes are anthropogenic behaviors that increase down dropping and flooding. Soils of ancient villages show that Luiseno and Cahuilla people populated the Santa Margarita watershed, as do their reservation-based and urban descendants today.
Eleanora (Doc) Robbins, PhD is a bio-geologist, retired to San Diego from the Washington, DC area. As a volunteer, she has run Science Explorers Club monthly since 2001 on Indian reservations in San Diego County. In this program, she teaches outdoors science to 5-11 year olds. Activities cover geology, hydrology, biology, botany, and soil science. Her degrees are BS (1964 Ohio State Univ.), MS (1972 Univ. Arizona), and PhD (1982 Penn State Univ.). She started her professional career in the Peace Corps as a geologist with the Geological Survey of Tanzania; on vacation, she mapped in the East African Rift Valley for Lewis Leakey. Then she was a researcher for the US Geological Survey for 34 years, working on mineral deposits, coal, and petroleum. In San Diego, she served as adjunct faculty for 14 years at San Diego State Univ. Her current research on the sulfur cycle of the San Diego River is with the San Diego River Park Foundation.
