Mrs. Vocelka was born Dec. 11, 1947, in Burlington, Wis., to Eugene and B. Weiss. As a young child, she would travel west with her parents where she would become enchanted with the landscapes she found there. She made the move west in 1967, where she took a summer job in Yosemite National Park at Wawona. Although she held many jobs, she was known most for her work as the research librarian for the National Park Service as well as the school librarian at Yosemite Elementary School. She is mentioned in hundreds of publications for her diligent research. She met the love of her life, Derrick Vocelka, in Yosemite, and they were married June 10, 1968. They had a daughter and lived in the park for 30 years.

She and her husband moved to Bishop in 1998 after a short stay in Auburn where she worked at Odyssey Books in Grass Valley. She was involved in Audubon, the Native Plant Society, and the Manzanar Historical Site. She worked at the Bishop Nursery.

Mrs. Vocelka is survived by her husband of 40 years, Derrick of Bishop; daughter, Sarah and adored son-in-law, Mitch Hendrickson, and beloved grandsons Caspar Vik and Duncan Muir of Grass Valley.

She was preceded in death by her parents, Eugene and B. Weiss.
