Mountains, she discovered that extinction and evolution of ancient species into newer variants was more prevalent in the middle of the continent because of the wider degree of seasonal changes; in contrast, coastal areas with more moderate climates supported older species such as the giant redwood. Her work also included studying drilled cores containing pollen from the
Miocene Epoch that revealed evidence of a tropical rainforest in the

As a professor of botany and forest sciences at the University of Washington, she directed the Quaternary Research Center, researched the forest history of the Pacific Northwest, and collaborated with Chinese paleobotanists. Leopold's work as a conservationist included taking legal action to help save the Florissant Fossil Beds in Colorado, and fighting pollution. She was the daughter of

Her research involved extracting pollen and spores from ancient rocks and sediments and comparing this evidence of fossil plants with those of modern specimens in order to infer what past landscapes and environments were like.

Leopold's research in
Colorado at the Florissant Fossil beds led her to become a leader in the effort to preserve the area containing this rich fossil evidence. The area was to be converted into a real estate development until she and several others filed suit. On August 20, 1969, the 6,000 acre area

On completing her Ph.D. in 1955, Dr. Leopold took a job with the United States
Geological Survey, where she worked for 21 years, from 1955 to 1976. She made important findings about the effects of climate on the evolution and extinction of prehistoric plant species. In her work in the Rocky
