    Trista Thornberry-Ehrlich

    Inspired by a curious father to read mineralogy textbooks at the age of 10, Trista has crafted a career that encompasses many of her interests: geology, ecology, history, education, maps, and art. Technical skills came with time and training, using platforms such as Adobe Creative Suite and ArcGIS Pro to bring natural science information together in intelligible and visually appealing ways. When she is not writing interpretive texts, performing geospatial analyses, making maps, or crafting graphics, Trista is usually learning languages, teaching English as a foreign language, running, cooking, traveling, and spending time with her husband and daughter.
