Hey Johnny,
I got wildflowers last night. The sun was breaking through storm clouds just prior to the sunset as I was just entering the park from the south end. That area is also blanketed with wildflowers, so I just stopped there to shoot. I never did get to see the area you shot in the daylight. I drove up to Jumbo Rocks as I had gotten a campsite there. I woke up to it snowing at 2:30 am, there was several inches on the ground. I tried to go back to sleep, but at 3am I saw that it had stopped snowing and the clouds were breaking up some and the moon was shining through and the also the stars were out. So I shot the rock and the Juniper for an hour or so, and then I ran over to Arch rock and shot it with the snow and the stars until 5am. Just as I was leaving there, the clouds came back in and it snowed more. I went back to Jumbo Rock and waited for sunrise, the snow stopped about sunrise, there was some color as the sun weakly poked through, but it was still cool. There was nothing more to shoot with the rock and juniper, so then I worked my way around and shot Split Rock, Skull Rock, and lot's of Joshua Tree's. Between 7am and noon, the sun would break out with that clearing storm cool light, and then next you know, it as back to the clouds moving in. This repeated itself at least 4 or 5 times, so I ended up with lot's of amazing light in all sorts of places in the middle of Joshua Tree.
So, yeah, it was awesome! In 16 hours I went from shooting wildflowers to snow and stars all in Joshua Tree.
