Welcome to the Geology PAC program. This is a program designed to introduce students to the geology of Great Falls and Mather Gorge. As a part of all PAC programs, students will come to Great Falls Park to learn in a park environment with a park ranger. The park visit takes approximately three and a half hours, including a lunch break for the students.
The pre visit activities can be downloaded by selecting the links below. If you are interested in scheduling a PAC program, visit the main PAC page or contact the park directly at 703-285-2965.

Exploring Geology – Formation of Great Falls is a curriculum-based program for upper elementary grades that teaches Earth Science. The program introduces the concepts of the rock cycle, examines the different types of rocks, and explores how Earth is dynamic. Great Falls is unique in that rock formations exposed in Great Falls Park are very rare in the region, making it a favorite spot for study. Besides the fact that all processes in the rock cycle are represented in the rock, the scenic beauty of the environment is awe inspiring, making the park an outstanding outdoor classroom.
Students study the basic principles of Earth Science in the classrooms, establishing a foundation for hands-on activities in the real world. An in-depth 4-hour on-site program offers students the opportunity to experience the natural world. It is the programs intent to provide children with lasting images of our dynamic Earth and the idea that national parks are fun places to visit and explore the natural world while at the same time demonstrating the importance of preserving our environment for future generations. Through cooperation with Park Rangers and educators, the program has the potential to reach children in deeper, more meaningful ways.
