She was an active member of the American Association of Petroleum Geologists (AAPG) for 56 years, and was an elected fellow of the Geological Society of America.
Elliott had initially enrolled in pre-med but switched her major to geology because she was inspired by Charles Decker, one of the founders of the AAPG.
[1] To continue her studies, she attended the University of Colorado, where she held a teaching fellowship and research grant in micropaleontology during which she worked on cretaceous shales.
After her husband's death in 1960, Elliott moved to Mobil's Oklahoma City office, where she worked on the stratigraphy of the Permian and the Arkoma basins.
When she died on July 7, 2001, at age 83, funeral services were held for her by her church communities in Dallas, Texas, where she lived at her death, and in her childhood hometown of Cordell, Oklahoma.
