Sparking Curiosity and Understanding of Our Natural World

The Sierra College Natural History Museum is a dynamic and awe-inspiring center for STEM learning initiatives. Located in the heart of Sewell Hall (the Science Building on Rocklin campus), the Museum and accompanying Planetarium has become a regional landmark for thousands of youngsters, students, teachers, and parents who come to engage, experience, and discover.

For more than 50 years, the Museum has provided inspirational scientific education to its students and the community. The Museum was initially funded by a special grant from Project Gold Mind and the Museum’s champion and department chair, R.A. Underhill, who oversaw the construction of exhibits based on the rising theme of ecology.
