Program Notes: Friday, March 10, 2023 at 7:30 PM.  Jurupa Mountains Discovery CenterPresented by Virginia Odem , Education & Grant Coordinator; Maribel Vargas, Museum & Store Coordinator; Wes Andree , Executive Director 

If you believe that children, and their families, regardless of their economic status, should have access to creative youth focused museums, then believe in Jurupa Mountains Discovery Center. JMDC is an Earth & Live Science Museum located in the foothills of the Jurupa Mountains in Jurupa Valley California. 

JMDC is on 82 acres with many fascinating facets. Our primary focus is our School Learning Expectations (field trips), which support California classroom standards. 

Walking gardens have dinosaur sculptures scattered within our cactus/succulent gardens, butterfly gardens and aloe fields. JMDC’s Granite Hill Nursery sells a wide selection of cactus, succulents, and plumeria for beginners and collectors. 

JMDC’s Museum of Discoveries has a unique collection of rocks, minerals, fossils and other curated items. Complimenting the museum is JMDS’s Gift Shop of Discoveries with rocks, minerals, fossils, toys, and collectibles for sale. Inside the gift shop is our Critter Corner, a Collection of 50 + reptiles, amphibians, and invertebrates to look at. 

With Staff assistance you can interact with many of the critters. No visit would be complete without “catching some dinosaurs to take home. Visit JMDC’s Dinosaur Trek to capture ten different dinosaurs when you visit.
