The top is drying out of my Joshua Tree

The top is drying out of my Joshua Tree. Why? I planted a seed in 1992 and moved it outside in 1998 after it had gotten about 2 feet. It has thrived, getting 13 foot tall. It never put out any arms, etc. I live in Idaho’s Treasure Valley where the temperatures are below zero in winter at times. Until this, it has been the talk of the valley. Any ideas what this is all about and how to cure it?

I would say it could be a combination of harsh winter and a watering issue (I suspect drought). It look as though Idaho is experiencing a drought – has it been very prolonged? In addition, the joshua trees as a whole are actually succumbing to climate change:

If you are in fact experiencing drought in your region, I would water your joshua tree and observe it for improvement.

You may also want to inspect your tree for damage by the agave snout weevil (the only serious pest of joshua trees):
