As the name suggests, this California preserve includes diverse ecosystems from the Colorado and Mojave Deserts to San Gorgonio Mountain. The passes have long been used by Native Americans, and the monument sits just north of the Morongo Reservation. So the area protects both diverse species and cultural heritage.

Jointly managed by the US Forest Service and the Bureau of Land Management, this land connects Joshua Tree with the San Bernardino National Forest and helps close the gap with the Santa Rosa & San Jacinto National Monument. While I-10 cuts between the two monuments, it’s not difficult to imagine a wildlife corridor being built over or under I-10 here someday, similar to the new 101 wildlife crossing near Santa Monica. There are existing I-10 underpasses in Arizona and New Mexico with plans for more.

I was curious about the nearby town on I-10 called Whitewater. Turns out the Whitewater River runs through the monument and picks up white silt in the sandy canyon. So, there’s no whitewater rafting on the river, although recent flash flooding closed a couple trails. The headwaters and upper reach is designated a wild & scenic river, then it turns into a recreational river in the wilderness, then flows through the monument and ends up in the Salton Sea.

While the national monument is fairly new, much of the land has been protected by environmental groups who negotiated donations to protect the area forever. The cabin above is a ranger station in a pretty campground in the canyon. It’s nice to know that there are such lovely places just off the interstate.
