Please note that the Museum will be closing at noon on Wednesday, September 9, 2026 for a staff appreciation event. (Art Institute classes are not affected by the closure.)
Milpitas Wash drains the Chuckwalla and Chocolate Mountains and flows into the Colorado River. This is one of the largest washes in California, nearly a mile wide at its lower end. Despite the large watershed, the wash carries water only once or twice a year because downpours are rare. Most of the trees are desert ironwoods. The vehicle tracks in the lower right provide scale.
