Larson Family at Scripps Institution of Oceanography, 1969

I was born and raised in southern California. My family moved to San Diego in 1970 when my father took a job at the Deep Sea Drilling Project (see the dedication for Volume 60 ). I attended Harvard for college (receiving the rare A.B. degree in engineering), and then returned to San Diego for graduate school. I moved to Colorado in 1990, which is where I met my husband George Rosborough.
