Interesting colors and contrast between #sedimentary layers and #igneous intrusions in the Gravel Hills of the #Mojave Desert.
From Tom Dibblee (1968),

the layers are part of the Pickhandle and Barstow formations laid down in the Miocene. The darker purplish rock is an intrusion of #rhyolitic #breccia.
If the rock colors appear familiar you may have seen similar combinations of these formations in the Opal Mountains, Rainbow Basin, and Calico Mountains near Barstow, CA.
