The space between Heaven and Hell has a tree The Gates of Heaven and the Gates of Hell.

The Joshua Tree has long been associated to that space, since the Mormons made the observation.

There are only two places in the world with Joshua Trees. Israel and 29 palms.

29 Palms also has the marine air/ground combat center.

Q is could have posted the whole piece of artwork vs the middle. The middle is the tree.

Perhaps we should watch the Marines.
