I was describing the top of Wildrose peak there -- one of the coolest views I've seen in my life. I want to go back and try Telescope peak, which is right next to it and a bit higher and more strenuous, sometime.
These hikes aren't nearly as hot as the valley, and probably manageable even in the summer. Much of Death Valley's heat comes from the air being more compressed the lower you go, so if you're 6000 ft up it's not that bad at all. Although, be careful.
A few hours later I was on a different ridge and a bunch of fighter jets flew through a canyon _below_ me. Death Valley is awesome. (although that may have been right outside of it?)
In the meantime, I wonder if there are any good photos of them? I wouldn't know what to search for.
