Joshua trees seen here are probably the furthest west in existence, or at least the ones across I-5 are. Used to be a lot of them in the little canyon that extends east of this point but a fire killed a lot of them. A few are still alive.
Very few trees were blooming during this visit.
The namesake of the park, Joshua Trees (Yucca brevifolia) are almost entirely limited to the northern Mojave section of the park. Mojave Yucca (Y. schidiger) are dominant in the lower elevation Colorado Desert section of the park.
There is at least one joshua tree in this picture (viewed from the ridge where the native paintings/glyphs are).
