Geologic Map Day

Celebrate Geologic Map Day on October 18, 2024! Welcome to Geologic Map Day, a special event designed to promote awareness of geologic mapping and its vital importance to society.

As an extension of the National Cooperative Geologic Mapping Program, Geologic Map Day focuses the attention of students, teachers, and the general public on the creation, study, uses, and significance of geologic maps for education, science, business, and a variety of public policy concerns.

Organizing partners of Geologic Map Day are the United States Geological Survey, the American Association of State Geologists, the Geological Society of America, and the American Geosciences Institute. The event is celebrated on the Friday of AGI’s Earth Science Week (, a public awareness campaign that reaches over 50 million people each year with educational resources, information, and activities promoting awareness of Earth science.
