In an interview with AAPG candidates, Stone states that she took a strong interest in geology in her first year of college. She decided to major in the field and was eventually encouraged by her professor to join the AAPG board. According to Stone, what sparked her interest was seeing the “organization to the solid earth beneath my feet”, as well as “being in the field, and seeing the relationships,” as opposed to reading about them in textbooks.^[1]
