The Mission of the Cal Poly Humboldt Natural History Museum, through its collections, exhibits, and programs, is to inspire an understanding and appreciation of the dynamic natural world. By exploring the museum, we hope visitors are inspired to get out and explore other magical places in northwest California. We also provide a learning laboratory for Cal Poly Humboldt students and regional K-12 students and teachers.
