Summary
- Isabel Bassett Wasson became an early woman park ranger in 1920.
- Mary J. Sullivan was the first permanent woman ranger in 1924.
- Women rangers connected science, education, and conservation.

The history of America's national parks includes often-overlooked women who served as rangers in the early years. Isabel Bassett Wasson, with her geology background, was appointed a park ranger in 1920, impressing officials with her ability to interpret geological features for visitors. This marked a shift in the ranger role, emphasizing education alongside resource protection.
While Marguerite Lindsley was long recognized as the first permanent woman ranger at Yellowstone, historical research has since revealed Mary J. Sullivan received a permanent appointment at Glacier National Park on July 1, 1924. This discovery has reshaped understanding of early female park service contributions.
These early women rangers, like Wasson and Sullivan, played vital roles in interpreting parks, connecting scientific knowledge with public understanding. Their work demonstrated that protecting national parks encompassed education and conservation, laying a foundation for greater female participation in diverse ranger roles within the National Park Service.
