Mojave River Valley Museum

Route 66 travelers often pass through the Mojave on autopilot, focused on the next iconic stop. The Mojave River Valley Museum slows you down and explains what you're driving through — the geology of the Cajon Pass uplift, the disappearing Mojave River that flows mostly underground and surfaces seasonally near Victorville and Afton Canyon, the Native peoples who used those water sources for millennia before the Spanish arrived, and the layered economic history of mining, ranching, railroad, military, and highway that shaped every town along Route 66 between Cajon Pass and the Arizona border.

The fossil collection is genuinely impressive — Pleistocene mammoth tusks, camel and horse bones, and other megafauna excavated from local quarries and arroyos demonstrate that the Mojave was a far wetter, greener landscape during the last ice age. Kids love this room. The Native American gallery is respectful and substantive, covering basketry, trade networks, rock art, and the Serrano and Vanyume peoples whose descendants still live in the region. The mining gallery explains the silver and borax booms that built Calico, Daggett, and Yermo.

The Route 66 corner is small but well-curated — focused on Barstow-area Mother Road history, including the Casa del Desierto Harvey House, the El Rancho Motel, and other landmarks. The volunteers can direct you to obscure local Route 66 sites and ghost-town remnants that aren't in the standard guidebooks.

From Victorville to Barstow is roughly 30 minutes north on I-15 (or longer if you take the parallel National Trails Highway / Route 66 alignment through Oro Grande, Helendale, and Lenwood — which we recommend). A natural Route 66 day combines the California Route 66 Museum in Victorville (morning), drive Route 66 north through Oro Grande with a stop at Elmer's Bottle Tree Ranch, lunch in Helendale or push to Barstow's Peggy Sue's 50's Diner, then afternoon at both the Mojave River Valley Museum and the Route 66 Mother Road Museum in Barstow's Casa del Desierto.

For families with kids, the fossil and Native American galleries here are a strong draw — kids who tolerate the Route 66 sign and motel exhibits in Victorville will be genuinely excited by mammoth bones. The museum is fully wheelchair-accessible, has clean restrooms, and a small gift shop with local history books, fossil replicas, and Mojave Desert field guides.

Combine your visit with a walk through Barstow's historic Main Street (still active Route 66 alignment), a stop at the Mother Road Museum across the railroad tracks at Casa del Desierto, and a meal at Peggy Sue's 50's Diner in Yermo (15 minutes east) or Slash X Cafe (only weekends, near Apple Valley). The full day showcases the breadth of the Mojave Route 66 experience.

Open daily 11am to 4pm, free admission, donations gratefully accepted. Parking is free on Virginia Way and in the adjacent municipal lot. The museum is closed major holidays — check the website before traveling on Thanksgiving, Christmas, or New Year. Restrooms are inside, gift shop is well-stocked with local history publications, and the volunteer staff are universally helpful and knowledgeable.

For researchers, the museum maintains a local history library with oral histories, photo archives, and out-of-print regional publications — appointments are recommended for serious research but walk-in browsing is welcome. Photography is allowed throughout the museum without flash. Group tours can be arranged with advance notice — popular for school field trips and Route 66 tour groups during peak travel season.

The 2026 Route 66 Centennial is bringing increased visitation to all Mojave museums — arrive at opening or in the early afternoon to avoid the busiest periods. The museum participates in coordinated Centennial programming with the Route 66 Mother Road Museum, the California Route 66 Museum in Victorville, and the Wigwam Motel in Rialto — pick up a Centennial passport at any of these locations and get it stamped at each.
